The 20B20UF.25 Low GVD Ultrafast Laser Mirror is 50.8 mm in diameter, 9.4 mm thick, and broadband optimized for 700 - 930 nm. This ultrafast mirror is ideal for use with ultrashort pulse lasers as a high reflectance beamsteering mirror at 45° angle of incidence. Careful thin film design and an advanced coating process results in a mirror with maximum reflectivity and bandwidth with minimum effect on pulse dispersion.
