CO2 Laser Cavity Silicon Total Reflector Mirrors
CO2 Laser Cavity Silicon Total Reflector Mirrors
These silicon total reflectors are quite similar to turning mirrors. However, durability of the coating is more critical because the total reflectors are exposed to the gas discharge and the extremely high laser power density inside the cavity. Therefore, the coating must have best-possible environmental resistance and low absorption in order to minimize thermal distortion.
- Durable coating for best-possible environmental resistance
- Light-weight Silicon (Si) substrate
- Low absorption See All Features

Total Reflector Mirror Coatings
MMR-P coating is a cost-effective way to maximize reflection (>99.90% for S-Pol), improve performance, protect highly-sensitive mirror surfaces and prolong product life. OEM-approved MMR-P coating provides the highest total random reflection available with superior P reflection (>99.80%) and total random reflection (>99.85%) and is suitable for both Cu and Si mirrors. This coating is internal cavity radiation resistant and allows for a phase shift tolerance of ±2@45° and >70% reflection for 630-670nm, for superior cutting and cleaning capabilities.
