The 10RQ00UB.2 low GVD 50/50 Beamsplitter for Ultrashort Pulses is specially designed to manage the femtosecond pulse to minimize the pulse dispersion and wavefront distortion of reflected and transmitted light. The beam splitter is for S-polarized light and is coated with UB.2 providing a 50-50 split at 45 angle of incidence from 700950 nm. The back surface has an antireflection coating to minimize surface reflection losses and eliminate ghost images. A thin UV grade fused silica substrate, with &lambda,/10 wavefront distortion, is used to reduce pulse dispersion from the substrate material. This 25.4 mm diameter beamsplitter is designed to minimize pulse dispersion and maximize bandwidth for beam sampling and autocorrelation measurements of ultrafast laser pulses.
