Coating Tables for cavity optics
Ophir’s High Reflection coating represents a superior solution for beam delivery and cavity optics used in high-power CO2 laser systems.
The use of coatings like HR is a cost-effective way to maximize reflection, improve performance, protect highly-sensitive mirror surfaces and prolong product life for superior cutting.
Ophir’s OEM-approved HR coating delivers higher reflection than standard coatings at CO2 laser 10.6μ wavelength :
HR Cavity optics:
Ophir’s combined PLM-HR and MMR-P coatings represent a superior solution for cavity optics
PLM-HR Mirror Coating provides optimized S-Pol reflection (>99.90% for S-Pol), with low enough P-Pol reflection (<93% P-Pol) to enable effective phase locking while still reflecting Maximum reflection at the desired S Polarization
It is internal cavity radiation resistant, suitable for both Cu and Si mirrors and can be used in a variety of different resonator type.
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.
MMRp coating is used as a supiorior quality replacement for ZERO Phase Shift, Total reflection mirrors within the cavity as its cost is only slightly higher than standard ZPS / ZPS HR coatings
