Broadband PBS 620-1000 nm — Model MPBS632

N-SF1, optimized for 620 nm-1000 nm, cube size 20.0 mm×20.0 mm×20.0 mm, extinction ratio >1000:1.

Overview

LBTEK mounts the 20 mm broadband polarizing beamsplitter cube (AR coating: 620nm-1000nm) 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.

Key Features

  • Extinction ratio (Tp:Ts) >1000:1
  • Spectroscopic film: Tp>90%, Rs,avg >95%
  • AR coating: Ravg<0.5% (6°input face, per surface)
  • Optical coatings: AR coating + beamsplitter film
  • Transmitted wavefront error: λ/4
  • Surface quality: 40/20
  • Beam deviation: transmission: 0° ± 5 arcmin; reflection: 90° ± 5 arcmin
  • Substrate: N-SF1

Applications

  • Laser polarization control and beam separation
  • Interferometry and polarimetry setups
  • Optical isolators and magneto-optic modulators
