Ophir introduces Innovative High Reflection (HR) Mirror Coatings to improve optics' lifespan and cutting performance
Jerusalem, Israel, 3 March 2015 – Ophir Optronics Ltd., a global leader in precision IR optics components and laser measurement equipment, announced today that the CO2 Laser Optics Division of its Optics Group has developed an innovative HR coating for use in high-power CO2 laser systems based on multi-mirror cavity optics.
Ophir’s High Reflection (HR) coating offers 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:
Types of High Reflection Coatings
90 phase shift >99.0%, compared to previous value of 98%. This coating is now supplied for Ophir's standard phase retardation mirror.
Zero Phase Shift >99.7%, compared to standard coating value of 99.5%.
Both coatings are suitable for both Cu and Si mirrors.
Both coatings allow phase shift tolerance of ±2@45° and >80% reflection for 630-670nm[LR1] (same or better than standard coatings).
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 resistant to internal cavity radiation, suitable for both Cu and Si mirrors and can be used in a variety of different resonator types
MMR-P [LR2] 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%).It is suitable for both Cu and Si mirrors.
This coating is resistant to internal cavity radiation and allows for a phase shift tolerance of ±2@45° and >70% reflection for 630-670nm, for superior cutting and cleaning capabilities.
MMR-P coating is used as a superior quality replacement for ZERO Phase Shift total reflection mirrors within the cavity, because its cost is only slightly higher than standard ZPS/ZPS HR coatings.
