Optical Window with anti-reflection coating

◦By anti-reflection coating with a dielectric multi-layer, it is reduced to less than 1% to 4% reflection loss of the glass surface.
◦Since we are using the high quality material, the image will not be distorted by the transmission of the glass, and the laser beam is not diffused.
◦When you insert an window perpendicular to the optical path of the laser, the angle of the transmitted beam will not be changed.
