Edmund Optics Inc. 20mm Diameter Laser Diode Mirror NT46-619

Over 95% Reflectance of Visible Laser Diode Light Ideal for Multiple Reflection Systems Coating Optimized for 633nm at 45° AOI These Visible Laser Diode Mirrors are specially coated to attain maximum reflection of visible laser diodes. Optimized for 633nm at a 45° angle of incidence, these mirrors provide 97% reflectance versus only 85 - 90% for standard first surface mirrors. This reduced loss is particularly important in multiple reflection systems, where loss can significantly impact system efficiency.
