The FemtoOptics Ultrafast Mirror is 25.4 mm in diameter and 6.35 mm thickness, λ/10 flatness, and 10-5 schratch dig. Designed for 45 degrees angle of incidence to have high reflection at 400 nm and high transmisison 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 duractions ranging from 9 fs to 12 fs, depending on the spectral shape.

FemtoOptics超高速电子镜直径25.4毫米和6.35毫米厚度,λ/ 10平坦,纯schratch挖。该反射镜设计成45度入射角,在400 nm处具有高反射,在800 nm处具有高透射,具有双色波束分离器或波束组合器的双重用途。该反射镜以400纳米为中心,带宽为80纳米,根据光谱形状,可支持最小脉冲持续时间从9 fs到12 fs。
