PRODUCT
Development and manufacture of precision optical film elements
Product classification
laser diaphragm
Laser diaphragm is also called laser protection window, which is mainly used in preventing splashing debris generated in laser cutting processing from damaging the lens. The anti-reflection coating with high damage threshold (>15J/cm2) is coated on the two surfaces of quartz glass to improve the transmittance, and achieve advantages such as high optical power, high resistance to laser-induced damage threshold, solid film layer, good degree of finish, small absorption, stable and reliable performance.
