National Vietnam Veterans Museum (NVVM)Functional Object - Miranda Lens Case, 1969
... Miranda Lens Case...Lens Case...Functional Object Miranda Lens Case Miranda ...Photographic equipment belonging to Pte Garry David Martin (2793230) was a National Serviceman with the Royal Australian Infantry Corps and served in Vietnam with 1 Australian Reinforcement Unit in March 1970, 6th Battalion, The Royal Australian Regiment from April 1970 to May 1970 and the 7th Battalion from May 1970 to March 1971. In an unusual twist of fate, being in Vietnam gave many young Diggers the chance to own the most up-to-date technology, things they could neither get nor afford in Australia. The American PX (Post Exchange) operated like a duty-free department store, stocking everything from toiletries, stationery and snack foods to radios, cameras and small electrical appliances. As a result, servicemen routinely photographed and filmed their activities. Many captured their tours of duty with Kodak’s newest creation – the handheld Super 8 movie camera, released in April 1965. Families in Australia often received these films by post for developing at home. So, they saw exactly the conditions in which their relatives and friends were living and fighting. Compact tape-recorders made it possible for those serving to send news home in talking letters, or to keep their diaries as voice recordings.Black leather-look vinyl cylinder with leather strap and tab with press stud closure.

... A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. ...A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. ...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.
