OPTOMAN’s Ultrafast IBS-coated Dichroic Mirrors are designed to provide precise wavelength separation, while maintaining high LIDT and minimal Group Delay Dispersion (GDD) for preserving pulse duration and handling high peak intensity of femtosecond and picosecond laser systems.

This harmonic separator is optimized for reflecting 230 - 290 nm DUV region at a 60° angle of incidence, and transmitting 460 - 580 nm, 760 - 830 nm, and 1100 - 1600 nm, providing precise wavelength separation for ultrashort laser pulses.
