摘要： A UV image forming optical system includes a collimating lens for collimating light emitted from a UV light source, an imaging lens for forming an image of the collimated light transmitted through the collimating lens, and a beam splitting optical system positioned in an optical path of the collimated light between the collimating lens and the imaging lens. At least one of the collimated light emitted from the collimating lens and the light transmitted through the imaging lens, reflected by a reflector and transmitted again through the imaging lens is made incident upon an external viewing optical system.

摘要： An optical recording and reproducing apparatus is provided with a light source that emits a beam of light, a rotatable head including a deflector that deflects the beam in a predetermined direction and an objective lens group which forms an image of the beam on an optical recording medium. The rotatable head rotates about an optical axis of the beam which is incident upon the rotatable head. A movable lens group, provided in an optical path of the beam between the light source and the rotatable head, is movable in at least an optical axis direction.
