Abstract
An image transmitting optical system comprising at least two bar-shaped lens components and constructed to have a numerical aperture enlarged by reserving an adequate space between an image of object to be transmitted and one of surfaces of the bar-shaped lens component which is located closest to the image of the object. In this image transmitting optical system, spherical aberration and curvature of coma are corrected by designing each of the bar-shaped lens components as a cemented lens component consisting of two bar-shaped lens elements.
