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.
