OPTOMAN’s Standard IBS-coated Dichroic Mirrors are engineered to provide precise wavelength separation by reflecting one wavelength while transmitting another, with minimal absorption and excellent laser induced damage resistance. Coated using IBS technology, these mirrors deliver long-term spectral stability, sharp edge transitions, and high extinction ratios between transmitted and reflected beams.

These mirrors are optimized for Nd:YAG I and II harmonics and Er:YAG I harmonic, reflecting 632 nm at a 45° angle of incidence, while transmitting 532 nm,1064 nm, and 2940 nm, providing precise wavelength separation for laser pulses.
