Abstract
PURPOSE: To compensate the spherical aberration of the light with a low incident height and thus to facilitate an easy focusing by providing a junction lens adjacently to the diaphragm installed within the lens system and by securing a specified relationship for the refractiva index, the curvature radius, etc. of the junction lens.
