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 reflecting 2940 nm at a 45° angle of incidence, and transmitting 1540 nm, delivering consistent, high-performance operation in Er:YAG laser systems.
