Abstract:
An optical system for scanning in which a laser beam emitted from a laser light source is modulated by an external modulator, which is provided as one of a plurality of optical elements, in accordance with an image to be recorded on a recording medium and is subsequently deflected in a main scanning direction by main scanning deflection means so as to scan and expose the recording medium, said optical system for scanning comprising:a first base member to which at least two optical elements sequentially disposed along an optical axis of the laser beam are mounted after the positional relationship between them is adjusted; and a second base member to which said external modulator, which is disposed adjacent along the optical axis to the optical elements mounted to said first base member, is mounted after the positional relationship between said external modulator and a single optical element is adjusted, said first base member and said at least two optical elements being the single optical element.
