The 20Q20UF.35S Super-Broadband Turning Mirrors is ideal for use with ultrashort pulses lasers as a high reflectance mirror at 45 angle of incidence for a very broadband wavelength range spanning almost 400 nm. Designed to reflect over 99.6% from 680 to 1060 nm, this mirror can be used with Spectra-Physics Tsunami laser. Careful thin film design and advanced coating processes result in a mirror with maximum reflectivity, maximum bandwidth and minimum effect on pulse dispersion. Exhibiting ultralow phase distortion and a slightly negative GDD across the tuning range, this mirror is optimized for S polarization.
