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. Textile designers used viewing lenses such as this to see how many threads are within a textile sample. It was important to count correctly, otherwise the enlarged final pattern would be out of alignment. Before compact lenses such as this, specialised glasses were used such as 8039.The viewing lens has a 3 fold design in order to fold up to be compact and easily transportable in a pocket while also working to provide its own stand when unfolded. The lens is black and contains one circular piece of magnifying glass on the top panel.Top panel. Words, scratched. NINOtextile calculations, textile design

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.

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.

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. Black metal head, silver coloured mount and black turned timber handle. Case has black leather outer lining and purple velvet and satin inner linings. Case hinged with snap closure.

These contact lenses represent some of the earliest lenses used in Australia. They were made in Germany and distributed in Australia.

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.
