ENLARGEMENT IMAGING DEVICE AND IMAGE SENSOR

摘要

When reducing the focal length of an image forming lens in order to miniaturize a device, or when increasing the distance between an objective lens and an image forming lens in order to achieve high spectral dispersion performance, a primary light beam inclination increases, and light receiving sensitivity declines, in a peripheral region of a field of view. Provided is an enlargement imaging device in which an image sensor is used in which the pitch of micro-lenses (the micro-lens pitch) is greater than the pitch of the light receiving apparatus (the light receiving apparatus pitch).
