118. Daguerre's Singlet Landscape Lens, c. 1839
Unsigned, but on the lens support is a written paper label in ink: 'DAGUERRE'S LENS 1829', and the same is written on the wood in pencil in another hand.
Planoconvex f10 singlet landscape lens of 380 mm focal length with brass pivoted lens cap sliding over aperture of 38 mm diameter set 60 mm in front of the lens. The lens barrel slides in mounting secured to rectangular mahogany lens panel. In appearance similar to the lens and support of the Daguerre-Giroux camera (1839) by Charles Chevalier, so perhaps the date of 1829 is an error.
Length 80 mm, diameter 90 mm
