Our window mirror is a comprehensive performance of good optical products. Window mirrors are used to isolate the physical space while allowing light to pass through and are usually coated with anti-reflection films to reduce light loss. Our laser window mirror uses sapphire as the substrate material, and its operating wavelength range is 355nm~2940nm. The front and rear surfaces of the laser window mirror are coated with anti-reflective film layer. For the natural light with incident Angle of 0° or 45°, their reflectivity can be as low as 0.25%, and their performance is excellent.
