Concave Mirror, Femtosecond Optimized, 250 mm FL, 25.4 mm, 600-1000 nm
The 10BV50EAG.1 Femtosecond Optimized Silver Mirror is a concave mirror with a radius of curvature of 500 mm. It is 25.4 mm in diameter, 6.35 mm thick, and broadband optimized for 540 - 1000 nm. This ultrafast mirror is designed for zero to 45 degrees angle of incidence for S and P polarization. The absolute value of GDD is an astounding less than 5 fs2 from 550 to 1050 nm. Ideal for use with ultrashort pulse lasers, this high reflectance beamsteering mirror gives R>99% 600-1000 nm at 0 deg AOI, Rp>98.5% 580-1000 nm at 45 deg AOI and Rs>99% 540-1000 nm. Careful thin film coating design and advanced coating processes result in a mirror with maximum reflectivity and bandwidth with minimum effect on pulse dispersion.
FemtoOpticsTM is the premier optics product line specifically optimized for femtosecond pulse manipulation. It consists of innovative, high quality, easy to use, cutting edge optical components and assemblies for industrial and research applications.
