Archimedes screw magnifier - 19th century photographer's magnifier for achromatic focusing
Photographer's focusing magnifier from the late 19th and early 20th centuries.
When taking a photograph, the photographer would use this focusing magnifier against the frosted glass of his camera to assess the sharpness of the image formed.
The magnifying glass can also be used to examine a print on a light-transparent support.
It is adjusted by means of a helical screw with several threads, known as an Archimedes screw, which allows it to be moved and thus adjusted more quickly than by pulling the tube, as is the case with other models.
This same instrument is featured in the April 1890 issue of theJournal of the Royal Microscopical Society, which presents the ‘DUBOSCQ photographic microscope’. In the top left-hand corner, you can see this photographer's loupe, the same model.
Unfolded height: 8.8cm
Height closed: 5.5cm
Diameter at base: 4.8cm Diameter at eyepiece: 3.5cm
This same magnifying glass was for sale in the March 1910 catalogue of Photo-Hall in Paris, which sold cameras and accessories at the time.
