Concave Mirror, Ultrafast, 50.8 mm Diameter, 1500 mm EFL, 700-930 nm

The 20Q1500UF.25 ultrafast concave mirror is an 2.0 inch (50.8 mm) mirror with 1500 mm EFL. Low GDD dielectric coated ultrafast mirrors can be used with ultrafast lasers like Spitfire, etc. to route and focus the laser beams. This mirror is designed to work between 700-930 nm for S-polarized and 730-870 nm for P-polarized light. The uncoated surface of this mirror is commercially polished to allow leaked light to be used for various pulse measurement purposes. .
