特徴とする光学系の湿度補償装置。In an optical system device in which a plastic lens is provided in the optical path of a projected laser beam, and the laser beam transmitted through the lens is reflected and projected onto a photoreceptor by a mirror, a humidity detection element is provided near the plastic lens. By moving the mirror relative to the photoconductor according to the detected value of the humidity detection element, the optical path length from the mirror to the photoconductor can be varied, and the diameter of the laser beam focused on the photoconductor can be kept constant. Mi) - An optical humidity compensation device characterized by being provided with a moving device.
