UV light is reflected efficiently by this coating, while visible and IR light are transmitted. It is mainly applied to excimer lasers and third and forth harmonic outputs of Nd:YAG laser. Requirement of Laser damage threshold is critical to coatings in UV. Our products exhibit extremely good reliability in this aspect.
