CO2 Laser Mirror
CO2 Laser Mirrors are precision reflective optical components designed to handle the high power density and long wavelength (10.6 μm) of CO2 laser systems. Manufactured from silicon, molybdenum, copper or ZnSe substrates with high-reflectance metallic or dielectric coatings, these mirrors combine high reflectance, excellent thermal conductivity and high laser damage threshold. Chenyu Optics manufactures CO2 laser mirrors for laser cutting, welding, marking and industrial material processing systems.
CO2 Laser Mirror Overview
CO2 Laser Mirrors are precision reflective optical components designed to handle the high power density and long wavelength (10.6 μm) of CO2 laser systems.
Manufactured from silicon, molybdenum, copper or ZnSe substrates with high-reflectance metallic or dielectric coatings, these mirrors combine high reflectance, excellent thermal conductivity and high laser damage threshold, making them suitable for demanding high-power industrial environments. They are widely used in laser cutting machines, laser welding systems, laser marking equipment and industrial material processing lines.
Chenyu Optics supports custom CO2 laser mirror manufacturing according to customer drawings, including custom diameter, substrate material and coating design for prototype and repeat production.
