The 20QM20EM.25 is a High Energy Excimer Laser Mirror, 50.8 mm in diameter, 9.65mm thick, and is coated for 308 nm, optimized for 45° angle of incidence.

High-Energy Nd:YAG Laser Mirrors are manufactured using high purity fused silica substrates and ultra hard dielectric coatings. This mirror has been tested and certified to withstand high-energy pulses and have a high damage threshold. Meticulous production procedures guarantee they will withstand fluences greater than 10 J/cm2 at 1064 nm. The coating is highly durable and will withstand repeated cleaning.
We offer Nd:YAG mirrors for the fundamental 1064, frequency-doubled 532, frequency-tripled 354.7, and frequency-quadrupled 266 nm laser lines at either 0° or 45° incidence angle. A dual-wavelength mirror for 1064 and 532 nm is also available. Reflectivity is greater than 99.7% for s-polarization and greater than 99% for p-polarization. These mirrors are available in 25.4 or 50.8 mm diameters.
