These are the Lenses from the Klimsch Commodore Cartographic Camera that was located in Lithographic Squadron at the Army Survey Regiment, Fortuna, Bendigo. The KLIMSCH Commodore camera was originally introduced to the Survey Regiment in 1953 and was the largest in the Southern Hemisphere. It was replaced with a new model of the same size in 1977. These lenses are from this new model. The new model with its computer-based interface provided productivity gains with improved speed and its consistent results led to less wastage in time and materials. Its variomat lens system provided improved retention of map feature linear weights during the camera reduction process. The camera which was specially made for the Australian Army in Germany was fully automatic and power operated. It was claimed to be one of the biggest automatic cameras of its type in the world. It was made to the specifications of the Royal Australian Army Survey Corps to assist in the production of the very high standard maps for the Australian Army. THIS KLIMSCH COMMODORE CARTOGRAPHIC CAMERA was in operation 1977 - 1997". It was a Precision Darkroom Camera especially suited for Cartographic Reproduction of Line, Continous Tone, Halftone and Colour Separation. Reproduction of Negatives and Positives from a variety of Reflection or Transmission Originals. Its characteristics were: Maximum Negative Size 1.27m sq, Copy Holder (Vacuum) 2m sq, Maximum Enlargement 400%, Maximum Reduction 13%, Automatic 60, 90 and 120cm Focal Length Lens, Transmission or Reflection Originals, Pulsed Xenon, Photo Flood or Fluorescent Tube Light Source, Maximum Reflection Original 1.3m x 1.85m, Maximum Transmission Original 1.3m x 1.85m, Exposure Light Monitoring System." The camera was superseded by computerized image manipulation software associated with the Automap system. These significant and extremely high-quality Lenses were retrieved by WYCOMBE Constructions Pty Ltd during the demolishment of the camera in 1997 and then mounted on a display board. See also Item 6189.4P for more photographs of the camera.Lenses from the Klimsch Commodore Cartographic Camera mounted on a very heavy timber display board. The display board contains an engraved plate that describes the technical characteristics of the camera."KLIMSCH COMMODORE CARTOGRAPHIC CAMERA 1977 - 1997", "FUNCTION: Precision Darkroom Camera especially suited for Cartographic Reproduction of Line, Continous Tone, Halftone and Colour Separation.

This case only includes spherical lenses and has no cylindrical lenses for correction of astigmatism. The lenses have no rims, which was unusual after 1900. The set appears to have had very little use as it is in excellent condition.This is a late example of a trial case comprising only spherical lenses. The trial frame is a very rare type.Small timber cased trial set of spherical lenses only. No rims on lenses. Case labelled with lens powers in dioptres and inches. Trial frame included of unusual design:each eye rim has a sprung top cover to secure lens in place. Nickel alloy. Fixed bridge stamped 62, tapered sides with loop ends. Also a lens handling tool (nickel alloy) to position a lens in front of patient's eye.Lens powers labelled in inches and dioptres.

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. Non-illuminated ophthalmoscope has concave mirror in round head with central sight hole.Hinged coccius clip attached to hold lenses.

A Fresnel lens is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use primarily in lighthouses.  Made from high-quality glass Fresnel lenses were used originally in lighthouses and later for many other applications They were later being used for automobile headlamps, brake, parking, and turn signal lenses, and many other applications. Fresnel lenses used in lighthouses were considered state of the art from the late 19th through to the middle of the 20th century. The subject item is a Fresnel replacement lens used in a ships navigation light. For lighthouses, these lenses have now been replaced with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. The lens design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The catadioptric form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source making the light visible from greater distances.The subject item at this time cannot be associated with a historical event, person or place, provenance is unknown, the item is a replacement for a ships navigation light and it is believed to have been produced before 1950.Fresnel glass replacement lens for a navigation lamp of a ship.

The power of the lens, +7.50 DS, suggests this might be a magnifying lens for near work rather than a quizzer for distance vision.Round gold rimmed quizzer with machine engraved lens rim. Turned ornamental stem with a small engraved swivelling ring at its end for a cord or ribbon. The lens is glass of power of +7.50 DS.

Single lenses were used to assist reading for many centuries before spectacles were widely available. This magnifying lens may be even older than its case. The simple, large glass lens is held in a hand-worked horn or bone rim. The leather case decorated with floral beadwork is typical of northern European styles c1850.This lens is significant for the collection as it is the earliest mounted single lens in the Kett Museum.Large, round, horn-rimmed reading glass, or magnifier lens, incorporating ring-shaped handle.
