The FemtoOptics Ultrafast Mirror is 25.4 mm in diameter and 6.35 mm thickness, &lambda,/10 flatness, and 10-5 scratch-dig. Designed for 0 degrees angle of incidence to have high reflection at 400 nm and high transmission at 800 nm, this mirror can have a double use of being a dichroic beamsplitter or beam combiner. Having a bandwidth of 80 nm centered at 400 nm, this mirror can support minimum pulse durations ranging from 9 fs to 12 fs, depending on the spectral shape.
