3Pcs 20mm Si Coated Gold Reflective Mirror Reflector CO2 Laser SI20MM

Item Specifics: ●Usually a complete beam path outside the laser tube requires three reflect mirror and a focus lens. Laser will loss when it travels, so the laser machine need a higher reflectivity mirror.
●Good Reflecive Ability, The Reflection of Cloudray Mirrors can Reach to 99.2%.
●Gold-Plated Coating Film,More Durable.
●Can Withstand 200 Watt Laser.
●Silicon and Molybdenum is the main material of reflect mirror. The molybdenum mirror does not need coating film , they are able to work in harsh environments.
●Silicon reflect mirror is coated with gold film, to improve the reflectivity of the mirror, then to improve the efficiency of the machine.
●For Molybdenum mirror, there is no coating on the surface, but the reflection is low, maybe 80%.
●For silicon mirror, it is coated with dielectric or golden film. Golden mirror is better than Mo mirror, as the reflection is higher.
