​ Homogenizers - Superior Optics and Coatings

Because excimer lasers produce high-energy pulses of ultraviolet light, the materials used to make the optics must be carefully selected and the optics themselves must be carefully designed. You can rely on our deep knowledge and many years of experience to deliver the exact solutions you need.
