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 tripod was used to measure the height of distant points relative to a known point used in surveying and construction. The older levels consist of a telescope fitted with a spirit level and, generally, mounted on a tripod. Modern levels are automatic.This tripod was used in the Kiewa Valley by a Mt Beauty resident.Wooden tripod with pointy ends and with metal hinges at the top to collapse. It has a leather strap attached by a button press stud towards the pointy end. This is to enable the legs of the tripod to be fastened together. cowley tripod; surveying; kiewa valley;

Adams jnr wrote many elementary scientific works, as well as on the use of mathematical instruments. He often combined in his written works with religious themes and scientific content, often against the prevailing thoughts of the time. According to one popular magazine of the time (Gentleman's Magazine), his works were often accused of "growing errors of materialism, infidelity, and anarchy". He started writing at a young age and developed a love for it, his main interests included math and science, these subjects he often expressed in his written essay's. Notable works from Adams are. An Essay on Electricity, and Magnetism (1784). Essays on the Microscope (1787). An Essay on Vision, briefly explaining the fabric of the eye (1789). Astronomical and Geographical Essays (1790). A Short Dissertation on the Barometer (1790). Geometrical and Graphical Essays, containing a description of the mathematical instruments used in geometry, civil and military surveying, leveling and perspective (1790). Lectures on Natural and Experimental Philosophy, in five volumes (1794).George Adams Sr and Jnr were both notable opticians and scientific instrument makers of the 18th century. Their contribution to scientific innovation and optical development cannot be underestimated.

Appears to be part of sighting telescope for artillery. Further ID information has been sought from various sources, in including the Royal Australian Artillery History Company. The RAAHC have been most cooperative and interested in attempting to identify the equipment of which this item is a part, but with no firm details on its use or history at the time of cataloguing. Detailed communication between RAAHC and MERSL are available from the latter.Off-centre ring part way along barrel has engravings for elevation (?), ranging from 57 to 69 (see 4th picture above). Actual numbers engraved are 57 63 69, with small engravings to mark each degree between these intervals.

Inside are two light sources, which illuminate the object to be projected. Usually this object would be a postcard, photo, or other printed matter, but objects such as coins or leaves could also be projected. The light is reflected through the lens, and the image is projected onto a wall or screen. The light sources are burners. (http://museumvictoria.com.au/collections/items/721025/mirroscope-magic-lantern-projector-buckeye-stereopticon-co-1910) A lens sits at the front of a black metal box, with electricity lead. Inside two electric light bulbs illuminate the object to be projected (usually an image or printed matter), but objects such as coins or leaves could be projected. The light is reflected through the lens, and the image is projected onto a wall or screen. Focus is achieved by moving the telescoping lens tube in or out. The mirroscope includes an early electricity socket.projector, magic lantern, episcope, mirroscope, film, theatre, entertainment, movie
