ABSTRACT:
A lens system disposed between the emitting area of a laser diode and a focal plane for focusing the output beam of the laser diode on the focal plane is disclosed, in which system, as regards a direction parallel to the lengthwise direction of the emitting area of the laser diode, the emitting area and the focal plane are conjugate, and a telescopic optical system is formed of the lens system to form a telescopic image indicative of the exit pupil of the lens system at an infinite distance and to make small the convergent angle of the laser beam incident on the focal plane.
