Nd:YAG Laser Mirror, High-Energy, 25.4 mm Diameter, 45°, 532 nm

UV Fused Silica High Energy Nd:YAG Laser Mirrors

The 10Q20HE.2 is a 25.4 mm diameter, 6.35 mm thick High Energy Nd:YAG Laser Mirror coated for the fundamental 532 nm wavelength. Its reflectivity at this wavelength is greater than 99% for both s- and p-polarization, and it is optimized for 45° AOI.

Newport's High Energy Nd:YAG Laser Mirrors feature ultra-hard dielectric coatings on UV Grade Fused Silica substrates to resist damage from high power lasers. The coating is highly durable and will withstand repeated cleaning.
