This book of lectures on optics & geometry by Isaac Barrow, from 1674, was published in London in Latin to make it available to scholars across Europe. Isaac Barrow (1630-1677) was a graduate of Cambridge (BA 1649, MA 1652) and a mathematician. He became Lucasian Professor of Mathematics at Cambridge in 1663 and was tutor to Newton. This book includes Barrow's studies in geometric optics and the nature of light; material that would have encouraged Newton's better known research.This book has historical significance as it details the contemporary development of the knowledge of optics in the late 17th century. It is quite rare as no other copies are listed on WorldCat for Australia.Book, bound in full calf leather of the period, about optics and geometry by Isaac Barrow, in Latin. It has a title page, 12 introductory pages and 151 pages of text divided into 13 "lectures". There are 13 fold-out figures illustrating geometric constructs. It is in good condition except that the front cover is at present detached.optics, geometry, isaac barrow

This 300 year old book deals with the theory of light and colour and with investigations of the colours of thin sheets, 'Newton's rings', and diffraction of light. Newton uses a wave theory of light and his corpuscular theory to explain his observations. Sir Isaac Newton (1643-1727) was a great figure in the history of optical science. His classic 'Opticks' was first published in English in 1704. This Latin edition of 1706 was published to satisfy a wider scientific audience in Europe. Newton was Lucasian Professor at Cambridge 1669-1693 and a fellow of Trinity College. He achieved fame as a creative mathematician and for his law of universal gravitation which explains planetary motions. He retired from research in 1693 to become a government official in London.This book is highly significant as a milestone in the study of optics. Although not a very rare book, only one other copy is listed by WorldCat in an Australian institution.Latin edition of Newton's 'Optics' translated by Samuel Clarke. This copy is bound in full calf leather of the period, 348 pages, with fold-out figures plus a 24 page appendix 'Enumeratio linearum tertii ordinis' and a 43 page appendix 'Tractus de quadratura curvarum'. It is in outstandingly good condition.Inscribed on the fly leaf in pencil is that this is the 2nd edition, the first in Latin, and that Newton gave Clarke 500 pounds for the translation.refraction, optics, newton, reflection

This book is the 1835 second edition of John Harrison Curtis' 1833 'A Treatise on the Physiology and Diseases of the Eye, containing a new mode of curing cataract without an operation, experiments and observations on vision, also on the inflection, reflection and colours of light together with remarks on the preservation of sight, and on spectacles, reading glasses etc'. The title page describes J H Curtis (1778-1860) as an oculist and also as an expert on the ear. His knowledge of eye pathology and surgery was poor but this was typical of the medical profession until the middle of the 19th century. He was 'aurist in ordinary' to His Majesty and other members of the royal family and his hospital and teaching appointments had more to do with the ear rather than the eye. The last pages of the book list his other publications most of which concern the ear and the deaf. He was the first person, in 1803, to apply speaking tubes to assist the deaf. He established the Royal Ear Hospital in Soho, UK in 1816.This book is of historic significance as it shows contemporary understanding of ocular pathology in the early nineteenth century. It is quite rare as no other copies of the second edition are known in Australia.'A Treatise on the Physiology and the Diseases of the Eye' by J H Curtis is book of 1835 bound in its original boards, in very good condition, 230 x 140 mm, 242 pages, second edition. There is a coloured plate facing the title page with three figures featuring an ingenious lift up section of a woman's face to show the blood vessels and nerves underneath. There is a philosophical introduction, a chapter on ocular anatomy, two chapters on diseases and their treatment, one on the nature of light and one on the preservation of vision. Cataract is treated by withdrawal of blood from behind the ear and the application of an ointment to an induced blister on the neck, with potash applied to the cornea daily.optics, ocular anatomy, ocular disease, physiology, cataract

It has been suggested that it is possibly part of the clockwork mechanism of the third order Fresnel lens, which was a component of the Chance Brothers lens system introduced to the lighthouse when the optics were upgraded in 1913, and subsequently removed in 1975. Further research may confirm its association with the lens and increase its heritage importance. The well-made brass fitting has second level significance as a possible former component of the clockwork mechanism manufactured by Chance Brothers in c.1912.Brass, round, knurled fitting.One end of the fitting has a cylindrical knob end with a smooth surface; the other has a broader cylindrical knob with a knurled surface to allow for gripping and turning.

Opera Glasses came into existence as a result of a long line of inventions, and further improvements upon those inventions. The process started in the year 1608 when a Dutch optician by the name of Hans Lipperhey developed the first pair of binoculars with a magnification capability of X3. Less than a year later, a well-known inventor and philosopher by the name of Galileo developed what became known as the Galilean telescope. Advertisements were first found for opera glasses and theatre binoculars in London as early as 1730 in the form of a long collapsible telescope. The "Opera Glass" as it was referred to; was often covered in enamel, gems, ivory, or other art and paintings. For almost 100 years opera glasses existed merely as telescopes. In Vienna, in 1823 the first binocular opera glasses and theatre binoculars began to appear. They were two simple Galilean telescopes with a bridge in the centre, each telescope focused independently from the other by extending or shortening the telescope until the desired focus was achieved, which was useful, yet very cumbersome. Two years later in Paris, Pierre Lemiere improved on this design and created a centre focus wheel. This allowed the focusing of both telescopes together. After this development, opera glasses and theatre binoculars grew in popularity because of the superior view they facilitated in opera and theatre houses. The beautiful design of the glasses themselves also added appeal to the opera-going crowd. By the 1850's opera glasses and theatre, glasses had become a must-have fashion accessory for all opera and theatergoers.Not very significant as not associated with a historic event or person and made during the first half of the 20th Century and many are still available and easily sourced.Vintage Pair of Opera Glasses, with cow bone barrels and eyepieces, both barrel pieces have split in them, both metal end barrels each have a minor dent, optics are pretty clear no mould although have very minor dust spots inside, they look like they were gilded at some point but most of this has rubbed off glasses have a black leather case with blue lining.

This item was used before the flexible sigmoidoscope (1996) and before the introduction of fibre optics late 1900s. The 1900s saw an incredible leap forward in the field of medical procedures. The ability to visually see what was happening within the human body (in real time) provided greater analysis about certain biological abnormalities during a greater time elapse than before. This procedure involved less trauma to the patient and greater flexibility to the Physician in treatment schemes. The rigid signoidscope, however provided the first visual of the colon in situ, but was highly invasive to the patient.This item was used in the Mount Beauty Hospital for qualified Physicians to use in their diagnostic evaluation of patients. This would not be an instrument used by a General Physician. This item is still a internal observatory method which may, in some instances, cause some minor complications. This item does point to the level of medical diagnostics, equivalent to those available in larger towns and cities, which brings this rural area (once considered to be an isolated region) to a higher level of medical care.This rigid 35 cm long sigmoidoscope (internal probe) is made of stainless steel outer hollowed rounded rod, which permits the use of both a fixed (very thin) lighting rod and two flexible cord lights access. Both the lighting rod and the flexible lights can be lowered within the main rod to allow the physician to see the colon at the bottom of the rod.These items are all contained within a specifically inlaid wooden box. The box has separate open compartments for the main instruments and a small lidded compartment containing replacement light bulbs. The hollowed tube permits the physician to visually observe the signoid (an S shaped part) of the colon.On the stainless steel main rod body are engraved the lengths of the body,in centimetres ,with numbers starting at the five centimeter mark and then every five centimetres up to the thirty centimetre mark. On the front inside rim of the box are two inlaid white plastic strips with black print, "ALLEN & HANBURYS Ltd" and the other "LONDON"medical diagnostics, sigmoidoscope examinations, medical examinations, hospital equipment

Before the introduction of electricity, lighthouses had a clockwork mechanism that caused the lens to rotate with a light source inside that was either powered by Kerosene or Colza oil. The mechanism consisted of a large weight attached by a cable through the centre of the lighthouse to the top where the cable wrapped around a barrel, drum or wheels that controlled the speed of the lights rotation by a clockwork mechanism. The keeper would crank the clockwork mechanism, which would lift the weight ready for the next cycle similar to an old grandfather clock mechanism. Once the weight lifted to its apex at the bottom of the first landing, the keeper would let it fall, which would pull on the cable, which would, in turn, operate a series of gears activating the rotation of the Fresnel optical lens, which would then rotate to create the lighthouse’s unique light speed of rotation characteristic. Creating a specific characteristic required a way to regulate the speed of the rotation, and was important as sailors could identify a particular light by its speed and time between flashes. The weight had to fall at a certain rate to create the proper rotation speed of the lens and a regulator within the mechanism accomplished this. History: From 1851, Chance Brothers became a major lighthouse engineering company, producing optical components, machinery, and other equipment for lighthouses around the world. James Timmins Chance pioneered placing lighthouse lamps inside a cage surrounded by Fresnel lenses to increase the available light output these cages, are known as optics and they revolutionised lighthouse design. Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution the light flashes. The noted English physicist and engineer, John Hopkins invented this system while employed at Chance Brothers. Chance Brothers and Company was a glass works and originally based in Spon Lane, Smethwick, West Midlands England. The company became a leading glass manufacturer and a pioneer of British glass making technology. The Chance family originated in Bromsgrove as farmers and craftsmen before setting up a business in Smethwick near Birmingham in 1824. They took advantage of the skilled workers, canals and many other industrial advances taking place in the West Midlands at the time. Robert Lucas Chance (1782–1865), known as 'Lucas', bought the British Crown Glass Company's works in Spon Lane in 1824. The company specialised in making crown window glass, the company ran into difficulty and its survival was guaranteed in 1832 by investment from Chance's brother, William (1788 – 1856). William owned an iron factoring business in Great Charles Street, Birmingham. After a previous partnership that Lucas had dissolved in 1836, Lucas and William Chance became partners in the business which was renamed, Chance Brothers and Company. Chance Brothers invented many innovative processes and became known as the greatest glass manufacturer in Britain. In 1848 under the supervision of Georges Bontemps, a French glass maker from Choosy-le-Roi, a new plant was set up to manufacture crown and flint glass for lighthouse optics, telescopes and cameras. Bontemps agreed to share his processes that up to then had been secret with the Chance Brothers and stayed in England to collaborate with them for six years. In 1900 a baronetcy was created for James Timmins Chance (1814–1902), a grandson of William Chance, who had started the family business in 1771 with his brother Robert. Roberts grandson, James became head of Chance Brothers until his retirement in 1889 when the company became a public company and its name changed to Chance Brothers & Co. Ltd. Additional information: Lighthouses are equipped with unique light characteristic or flashing pattern that sailors can use to identify specific lighthouses during the night. Lighthouses can achieve distinctive light characteristics in a few different ways. A lighthouse can flash, which is when brief periods of light interrupt longer moments of darkness. The light can occult, which is when brief periods of darkness interrupt longer moments of light. The light can be fixed, which is when the light never goes dark. A lighthouse can use a combination of flashing, oscillating, or being fixed in a variety of combinations and intervals to create individual light characteristics. It is a common misconception that a lighthouse's light source changes the intensity to create a light characteristic. The light source remains constant and the rotating Fresnel lens creates the various changes in appearance. Some Fresnel lenses have "bulls-eye" panels create beams of light that, when rotated between the light and the observer, make the light appear to flash. Conversely, some lenses have metal panels that, when rotated between the light and the observer, make the light appear to go dark. This Dioptric clockwork apparatus used to turn a lighthouse optical lens is very significant as it is integral to a lighthouses operation, we can also look at the social aspect of lighthouses as being traditionally rich with symbolism and conceptual meanings. Lighthouses illustrate social concepts such as danger, risk, adversity, challenge and vigilance but they also offers guidance, salvation and safety. The glowing lamp reminds sailors that security and home are well within reach, they also symbolize the way forward and help in navigating our way through rough waters not just on the oceans of the world but in our personal lives be it financial, personal, business or spiritual in nature. Nothing else speaks of safety and security in the face of adversity and challenge quite the way a lighthouse does.

The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation.    John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that are represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollonds early library telescopes and its connection with one of England's 18th-century pioneers in optical development is in itself a significant and an important item to have within the collection.

This Dollond Day or Nigh telescope was designed to be used in any light conditions, as its name implies. Telescopes are optical instruments designed to make objects appear to be larger or closer.

He applies for a patent on his invention and this becomes the first documented creation of a telescope.

This collection of three photos of the Australian information Technology Award (AITA) won by the Royal Australian Survey Corps (RA Svy) AUTOMAP 2 computer-based map production system, was taken in 1984 at the Army Survey Regiment, Fortuna, Bendigo. The following article appeared in the ARMY Newspaper on Thursday 21st February 1985. ‘In computerised map production. Survey soldiers lead the world. BENDIGO: Army surveyors have been put on the map as world leaders in computerised map production following the Australian information Technology Awards. RA Svy won the Computer Assisted Draughting – Mapping section for its Automap II System which has created considerable interest among overseas defence experts. The award for the digital mapping system was accepted by OC Air Survey Sqn, MAJ Rob John, who said it was a great morale-booster for the soldiers of the Bonegilla (sic)* -based Army Survey Regiment. "Setting up a state-of-the-art system like Automap II. is an enormous task, " he said. "We started in August 1983 and it's only recently that we have achieved production results. "We were all very pleased to have our efforts recognised in this way. “Of course, credit must also go to the Intergraph Corporation for manufacturing the system and carrying out most of the development." RA Svy is responsible for producing all of Australia's maps used for defence purposes. Its topographical maps have a scale of 1:50,000 or 1:100,000 although Automap II has the capability of producing smaller scale maps - down to 1: 2,000,000. Automap II consists of three computers and three sub-systems: input, raster scanning, and graphic edit. The input sub-system has eight stereo plotters, two interactive graphic workstations and a system manager workstation. The stereo plotters use superimposition optics to digitise features from aerial photographs. It incorporates a voice recognition system so the operator can simply say "House", "Windmill", etc; and the relevant feature will be incorporated in the digital picture. Individual map separations are scanned and converted by the raster scanning sub-system to a digital raster image. This image is then converted to a graphics file in Intergraph format.’ *Note – the Army Survey Regiment was located in Bendigo, not Bonegilla as incorrectly stated in the article.

This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. John Browning was particularly well known for his scientific advances in the fields of spectroscopy, astronomy, and optometry. Between 1856 and 1872, Browning acquired provisional patents for designs of numerous scientific instruments. He was also the recipient of an award at the 1862 International Exhibition held in London. Also recognised for his temperature-compensated aneroid barometer. Browning's scientific instruments were used in physics, chemistry, and biology. The products he designed and manufactured included spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmologist, and electrical equipment such as electric lamps. John Browning was born around 1831 in Kent, England. His father, William Spencer Browning, was a maker of nautical instruments. John Browning's great-grandfather was also an instrument maker as well as John’s brother Samuel Browning of the firms Spencer & Browning and Spencer, Browning & Rust, who also manufactured navigational instruments. The latter firm was in operation in London from 1784 to 1840 and was succeeded by the firm of Spencer, Browning & Co. John Browning initially intended to follow the medical profession and entered Guy's Hospital, a teaching hospital and a school of medicine. Despite having passed the required examinations, however, he abandoned his plans. Instead, he apprenticed with his father, William Spencer Browning. At the same time, in the late 1840s, he was a student attending the Royal College of Chemistry several days per week.
