1. Single Layer MgF2 Anti-reflection Coating Magnesium fluoride(MgF2) is probably the most widely used thin film material for optical coatings. Its performance is not outstanding but represents a significant improvement over an uncoated surface. It is the most commonly used, low-cost anti-reflection coating, and widely used in Lens & Prism, Input & output surface.
R<1.0%@532nm
2. MultiLayer Sharp “V” Anti-reflection coating It can reach the lowest reflectivity at a center wavelength, and is widely used in single laser wavelength or multiple, closely spaced wavelength system.
R<0.2%@1064nm
3. Multilayer Broadband Anti-reflection Coating
It is ideal for a wide range of multi-wavelength laser and white light application. Excellent performance over a broad range of spectrum. Coating performance is sensitive to angle of incidence.
R<0.6%@450-650nm,R<1%@420-700nm
4. Dual-Wavelength Anti-reflection coating Dual-wavelength Anti-Reflective Coating allows two center wavelengths radiation to pass through the substrate with high transmittance.This coating is often used in frequency doubling systems or the other multi-laser output systems,such as the Nd:YVO4 laser(1064nm)and its second harmonic generation(532nm)green laser.
R<0.25%@1064nm&R<0.5@532nm
