The low-loss mirrors have high-damage thresholds, thermal stability, and low-wave-front distortion. All mirrors are designed for a 45° angle of incidence and feature low polarization dependence. They have a thin-film dielectric coating on fused-silica substrate, offer 10-5 surface quality, and come in diameters of 12.5 mm and 25mm. The mirrors are damage tested using 10-ns-long excimer laser pulses at the specified wavelengths.
