China CO2 Laser Reflecting Lens Si with Gold Coating Diameter, Find details about China CO2 Lens, Reflective Lens from CO2 Laser Reflecting Lens Si with Gold Coating Diameter
At present, Silicon reflector with good optics characteristics is mostly used. Dielectric film reflector is a new total reflection mirror with the single crystal Si as substrate and coating dielectric material on it to reflect CO2 laser. It has advantages of a high reflectivity, light weight, wipe-resistant and resistant to oxidation and etc.
