Abstract
An optical system for scanning which facilitates, at a time of assembling a plurality of optical elements forming an optical system for scanning, adjustment of positional relationships between the optical elements so that an appropriate laser beam is irradiated. In a light source unit, an SHG module and a collimator lens are assembled on a first base which is formed of covar, and this first base is mounted via an adjustment spacer to a second base at one end thereof in a longitudinal direction. An AOM is mounted to the other end of the second base. In this way, in this light source unit, adjustment of the positional relationships between the optical elements at a time of assembly is facilitated. In addition, regardless of whether an impact is applied at the time of assembly or whether a temperature or the like changes after assembly, an appropriately modulated laser beam can be irradiated.
