Stereo camera; has right and left objectives spaced between spacing between centres of two images and spacing between optical axes of objectives for shortest picture distance
Stereo camera; has right and left objectives spaced between spacing between centres of two images and spacing between optical axes of objectives for shortest picture distance
The camera has right (10R) and left (10L) objectives. The objective spacing is approximately halfway between a spacing corresponding to the spacing (Pf = Plmax) between the central points of the two images and a spacing between the optical axes (Pl) at which the photographic area of the objectives corresponds to the shortest picture distance. An optical or magnetic device may be included to mark the date on the lower or upper edge of the film.
