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. 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 is 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 Dollond's early library telescopes. Its connection with one of England's 18th century pioneers in optical development makes it a significant and an important item to have within the collection.Telescope: Dollond's Telescope, Day or Night model navigational instrument.

Nino Corda was a Geelong based textile designer who worked at various textile mills between 1957 & 2003. He travelled the world in search of the latest fashions and techniques and developed timeless designs that were much loved by Australians. These items are on rotational display at the National Wool Museum’s ‘In the Factory’ exhibition. For many years, Nino also worked as part of the Honorary Staff of the National Wool Museum. His passion for the world of textiles provided energy and knowledge to the visitors and staff of the museum. Although Nino has now retired from his honorary position and has hung up his Australian Tartan vest, these items will continue to serve the community in sharing the stories of Australian Textile design.Custom made wooden hinged box with a hook latch.

Richard Liebreich of Germany invented his design of ophthalmoscope in 1855. This example is complete in its case with Coccius lenses and condensing lenses. Early ophthalmoscopes required an external source of illumination, eg lamp or candle, and light was reflected into the eye to be examined by the mirror on the ophthalmoscope. The earliest versions of the Liebreich ophthalmoscope used a polished metal surface to reflect light; glass mirrors were introduced in 1870. A condensing lens was held in front of the patient to view the image. A Coccius lens could be clipped into the holder to counter ametropia of user or subject.This Liebreich ophthalmoscope is significant for the collection as it is the only complete example of the three held in the collection.Cased Liebreich ophthalmoscope with 5 small coccius glass lenses and 2 glass condensing lenses.

Francis Powell (1861-) and Francis Hanmer (1858-1925) founded Powell and Hanmer Ltd in the Summer of 1885 for the manufacturer of bike and carriage lamps. Their first advertisements began to appear in November of 1885. In 1890 they lodged a Patent for “velocipede” lamps to be used by lightweight wheeled vehicles propelled by a rider, such as a bike, tricycle and railroad handcar. In April of 1913, they were selling headlamps for cars and in 1914 built their second factory manufacturing dynamo lighting sets in Rocky Lane Birmingham, also for the production of dynamos for motor cars. Then in 1929 Powell and Hanmer Ltd, was acquired by the Lucas company which was at that time the main competitor for the manufacture of non-electrical equipment for cycles and motorcycles. When a director of Powell and Hanmer joined the board of Austin motor cars, Lucas feared that Austins might encourage Powell and Hanmer to start to produce electrical equipment for supply to the company and as a result this association might affect Lucas's business with other large vehicle manufacturers. As a result, Lucas made an offer to Powell & Hanmer and purchased the business for £500,000. Carbide lighting was used in rural and urban areas of Australia which were not served by electrification. Its use began shortly after 1900 in many countries and continued past the 1950s. Calcium carbide pellets were placed in a container outside the home, with water piped to the container and allowed to drip on the pellets releasing acetylene. This gas was piped to lighting fixtures inside the house, where it was burned, creating a very bright flame. Carbide lighting was inexpensive but was prone to gas leaks and explosions. Early models of the automobile, motorbike and bicycles used carbide lamps as headlamps. Acetylene gas, derived from carbide, enabled early automobiles to drive safely at night. Thick concave mirrors combined with magnifying lenses projected the acetylene flame light. These type of lights were used until reliable batteries and dynamos became available, and manufacturers switched to electric lights. Acetylene lamps were also used on riverboats for night navigation. The National Museum of Australia has a lamp made in about 1910 that was used onboard the PS Enterprise, an 1878 Australian paddle steamer, currently owned by the National Museum of Australia in Canberra. It is still operational, and one of the oldest working paddle steamers in the world, listed on the Australian Register of Historic Vehicles.Acetylene Carbide lamp, Model “Panther” distinct patterned side red and green lenses.
