DM430 Dichroic Mirror | 45° AOI, 375–424nm High Transmission

DM430 Dichroic Mirror | 45° AOI, 375–424nm High Transmission

The DM430 is a precision 45° angle of incidence (AOI) dichroic mirror engineered for high-performance UV-Vis wavelength separation. As part of OPTOStokes’ comprehensive dichroic mirrors portfolio, this component delivers exceptional spectral consistency: average transmission greater than 95% across the 375–424nm band, and less than 2% transmission for deep blocking from 442nm to 700nm. Fabricated with high-purity optical substrates and durable dielectric coatings, it is optimized for demanding optical setups requiring reliable beam splitting, wavelength combining, and spectral separation.
