N-SF1, optimized for 900 nm-1300 nm, cube size 10.0 mm×10.0 mm×10.0 mm, extinction ratio >1000:1.
Overview
Unmounted broadband polarizing beamsplitter cube with AR coating (900nm-1300nm, Ravg<0.5%) on all four faces. One right-angle prism is coated on its hypotenuse with a beamsplitter film; the coated prism is marked with a pencil dot on its ground top face. For optimal optical performance, the input beam should enter normally on the right-angle face of the coated prism. Also available are cube-mount adapters (e.g., CM-3) that hold the 25.4 mm cube and provide compatibility with 30 mm cage systems.
