This coating is delicate, with a very thin layer of MgF©üover the aluminum film to prevent oxidation. These will not with-stand high energy excimer laser radiation. Clean carefully with methanol or acetone.

Our Standard Mirrors, with protective silicon monoxide overcoat on the aluminum film, meet eraser and adherence tests, with reflectance greater than 86% throughout the visible spectrum. Because of a small absorption dip near 800nm, we recommend our IR Mirrors for use with NIR sources.

Our Infrared Mirrors have hard, scratch-resistant gold mirror coatings giving a maximum of reflectance throughout the near and far IR to an average of 98.5%.

This aluminized Mirror has dielectric over layers which enhance reflectance in the visible spectrum to an average of 95% and which increases to 98% in the IR.

These interferometer-quality mirrors are coated with our High-Reflectance Coating.
