Optical system for digital camera with intermediate mirror arrangement to reflect intermediate image to image take-up device

摘要

Lens (1) creates intermediate image of object in plane (E). Intermediate imaging system (3) formed as 1:1 optics, forms intermediate image on image take-up device (8). Concave (10) and convex mirrors (9) are arranged so intermediate image is reflected on convex mirror once and twice on concave mirror. Optical path distance from plane to mirror (9) is same as from mirror (9) to take-up device (8).
