CO2 Laser Mirror SPT 0.75-0.12
Reflectors, also called total-reflection mirrors, commonly use molybdenum (Mo), copper (Cu) or silicon (Si) substrates. Molybdenum withstands harsh conditions, has long life and high power handling, needs no coating and tolerates wiping, but has lower reflectivity. Copper mainly suits high-power CO2 lasers. Silicon is the most common coated-mirror substrate, with good optical/thermal properties and high reflectivity. Sipait Laser's silicon mirrors reach 99.8% reflectivity, leading the laser industry.
