Ultra Broadband・Broadband Dieletric Half Mirror / PMH_PSMH
We offer Half-Mirror optics designed for use in Ultraviolet, Visible and Infrared wavelengths. They can be used for both transmission and divergence of multi-wavelength lasers and white light sources.
Ultra broadband half-mirrors are used for spectrometry applications.
