3Pcs Reflective Mirror Reflector Si Coated Gold for CO2 Laser Cutting Engraving

Description: Si Coated Gold Reflective Mirror Reflector Can Withstand 200 Watt Laser. Specification: Material: Gold-Plated Silicon Diameter: 20/25MM (1cm=0.39Inches) Features: 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. Package Included: 3 x Si Coated Gold Reflector Note: 1.Please allow 1-3cm error due to manual measurement.
