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 266 nm at a 45° angle of incidence, while transmitting 532 nm and 1064 nm, providing precise wavelength separation for laser pulses. With reflectance for IV harmonic and transmittance for I and II harmonics, this filter is optimized for Nd:YAG based laser systems.
