Broadband Polarizing Beamsplitter Cubes, AR Coating: 900 nm-1300 nm — Model MPBS633

N-SF1, optimized for 900 nm-1300 nm, cube size 20.0 mm×20.0 mm×20.0 mm, extinction ratio >1000:1.

Overview

The 20 mm broadband polarizing beamsplitter cube (AR coating: 900nm-1300nm) is mounted inside a cubic housing compatible with 16 mm cage systems. A scribe line on the top face marks the beam direction. M3 threaded holes on the side allow connection to 16 mm cage systems via a Ø4 mm cage-compatible mounting post. Four SM05 internal-thread ports accept 12.7 mm lens tubes. M4 threaded holes at the base support post mounting.
