Name/TitleBrew­ster Stere­o­scope, Claudet Patent, Pris­mat­ic Lens­es with Stor­age Box

About this objectA Brew­ster-type stere­o­scope is a refract­ing hand-held stere­o­scope intro­duced by David Brew­ster in 1849. The device was lat­er devel­oped into a view­er with an enclosed hous­ing. This mod­i­fi­ca­tion occurred large­ly in response to the use of daguerreo­type stere­oviews, which exhib­it­ed high sur­face reflec­tiv­i­ty and there­fore required shield­ing from ambi­ent light. A hinged lid was added to the top of the view­er in order to direct inci­dent light onto the daguerreo­type and, sub­se­quent­ly, onto paper stere­oviews. Jules Duboscq lat­er incor­po­rat­ed a ground glass ele­ment to enable illu­mi­na­tion of glass stere­oviews by trans­mit­ted light.

Claudet designed sev­er­al improve­ments to the stere­o­scope. These were record­ed in two patents con­tain­ing dif­fer­ent tech­ni­cal ideas. His sec­ond patent, no. 515, describes curved side pan­els for the Brew­ster-type stere­o­scope intend­ed to reduce inter­nal reflections.
