C02 Laser Mirror Si Material (Black Coating) The silicon mirror is a silicon substrate, which has good optical and thermaproperties. After coating a reflective film on the silicon surface, it can greatly improveits reflectance, which is approximately 99.6%, which can almost avoidthe loss caused by reflection. Product Structure Made of high-quality silicon anti-material, black coating, reflection reaches 99.6%. Anti-wear process,the lens life is 50% longer than others Material upgrade,higher power withstand Product Parameter Product Detail Laser Path
