UV image forming optical system and lens for UV radiation |
摘要 |
A UV image forming optical system includes a collimating lens which collimates light emitted from a UV light source, and an imaging lens which forms an image of the collimated UV light transmitted through the collimating lens. A rear focal point of the collimating lens adjacent to the imaging lens is located closer to the imaging lens than a last lens surface of the collimating lens on the light emission side. A front focal point of the imaging lens adjacent to the collimating lens is located within the imaging lens. A lens system for UV radiation is also provided, which can be used as an imaging lens for the UV image forming optical system.
