PHOTOGRAPHING DEVICE PROVIDED WITH HOLOGRAM

PURPOSE:To observe bright and good finder image while shortening an entire optical length by arranging a fixed hologram as a light splitting means appropriately set on the optical path of a photographing lens. CONSTITUTION:The phase-type hologram 7 is arranged on the optical path of the photographing lens 20, a luminous flux made incident on the photographing lens 20 is split to plural luminous fluxes by the hologram 7, and an object image is formed on a prescribed surface 6 by using one of the luminous fluxes. An aberration correcting member to correct the aberration of diffracted light emitted from the hologram 7 is especially arranged on the optical path of the luminous flux which is diffracted and split by the hologram 7. Thus, the fixed hologram as the light splitting means appropriately set on the optical path of the photographing lens 20 (including a space photographing lens 20 and a photosensitive surface 6) is arranged. Therefore, the luminous flux for photographing having high transmissivity can be obtained and also the bright and good finder image can be observed while shortening the entire optical length.
