The 10Q08-03UF.BS90 is a dielectric coated beamsplitter for splitting P polarized beams with pulses 25 fs and less. Designed to work from 730 to 870 nm at 45 degrees angle of incidence, 90% of the P polarized input will be reflected and the remainder transmitted. The broadband partially reflecting coating introduces negligible GDD upon transmission and reflection. Special care should be taken when mounting the beam splitters, since mechanical tension may lead to surface bending.

10 q08-03uf。BS90是一种介电涂层分束器，用于分离脉冲25 fs及以下的P偏振光。设计工作范围为730 ~ 870 nm，入射角45度，90%的P极化输入将被反射，其余的将被传输。宽带部分反射涂层在传输和反射时引入可忽略的GDD。安装分束器时要特别小心，因为机械张力可能会导致表面弯曲。
