Extremely broad wavelength range
670 nm to 1340 nm
Covers the full bandwidth of the Spectra-Physics Insight TM Laser
Superior reflectivity 99.6% +
Minimum pulse dispersion
The design of this mirror has been optimized for use with ultrashort pulse lasers as a high reflectance mirror at 45° angle of incidence for a very broad wavelength range. Designed to reflect over 99.6% from 680 to 1340 nm, this mirror can be used with Spectra-Physics Insight TM lasers. Careful thin film design and advanced coating processes result in a mirror with maximum reflectivity, maximum bandwidth and minimum pulse dispersion. These mirrors are available optimized for S or P polarizations.
