Abstract
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.
