MULTI-SPECTRUM IMAGE PICK-UP DEVICE AND ADAPTER LENS

摘要

There is provided a multi-spectrum image pick-up device having different photo-sensitive characteristics of at least four bands. The device includes: an image formation optical system (10); a branching optical system (12) for branching an image light flux obtained by the image formation optical system into a plurality of light fluxes and again forming an image by the branched light fluxes on the division image formation surfaces (30a, 30b); and a camera unit (14) including a single-plate color imaging element (16) having an image formation position on the division image formation surfaces.
