Fresnel Apparatus

Description
Augustin Fresnel (1788-1827) was a French physicist who, in 1821, announced that compressed glass causes double refraction of light passing through it, thus behaving in this regard as unstressed Iceland spar. This device demonstrates that phenomenon. The “J. Duboscq-Soleil / rue de l’Odeon 21 / à Paris” signature refers to Jules Duboscq, an instrument maker who apprenticed with J. B. F. Soleil, and used the “Duboscq-Soleil” signature for a brief period around 1850.
