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.

This hand-held signalling lamp could have had a number of uses. It could have been used by groups such as the Boy Scouts or most likely was used by local air raid wardens and other military personnel in World War Two. Its large face and the reflecting mechanism would have made it useful over a long distance.This lamp is of historical interest and is retained for display and research purposes.This is a cylindrical metal lamp with a clear glass front attached to the lantern by metal screws. The lantern has been painted black. There is an electric bulb behind the glass and a reflector disc behind the bulb. A handle, attached to the metal body, has two strands of electrical wiring at its end. The handle includes a finger clip, which, when pressed, produces a signal inside the glass area.signalling lamp, world war two military equipment

The photograph was submitted to the Indigo Shire Photo Competition by Kathy Adamo in the 1980s. The photo depicts two old gas lamps outside the Court House in Beechworth. The Court House was built in 1856 after Beechworth became known as the legal headquarters in northeast Victoria. The Court House has held a number of trials over the years including many high-profile cases such as the Ned Kelly Trials.Black and white rectangular photo printed on paper mounted on black card.Reverse: TO Indigo Shire Council Photo Comp / Title 'Lit By A Bygone Era' / 05.
