High-Power Laser Line Polarizing Beamsplitter Cubes — Model MPBS24-808-HP
UV Fused Silica, PBS cube, optimized for 808 nm, cube size 25.4 mm×25.4 mm×25.4 mm, extinction ratio >2000:1.
Overview
LBTEK provides multiple operating wavelengths from 266 nm to 1550 nm. LBTEK mounts the 25.4 mm high-power laser line polarizing beamsplitter cube inside a cubic housing compatible with 30 mm cage systems. A scribe line on the top face marks the beam direction. The housing provides M3 threaded holes on the side for compatibility with 30 mm cage systems, and four SM1 internal-thread ports for simultaneous compatibility with 25.4 mm lens tubes. The base of the cube also provides M4 threaded holes for post mounting.
