Image forming optical system for semiconductor laser

摘要

An image forming optical system for a semiconductor laser which forms an image of a semiconductor laser as a light source through an image forming lens, wherein the image forming lens is so disposed that it maintains the original divergent point of the semiconductor laser in the vertical direction and the image forming plane in a conjugative relationship, and that the image forming magnification beta in the vertical direction satisfies the following relationship of beta = gamma xsin theta OxFeff (1.2
