Flat polarized spectroscopic coating(VIS/NIR)

Flat polarized spectroscopic coating(VIS/NIR)
  • 400nm≤λ<2.0μm

Flat polarized spectroscopic coating(VIS/NIR) can effectively split incident depolarized monochromatic beam to S and P polarized quantity, extinction ratio of launched beam(Tp/Ts) over 200:1. The material used for flat polarized spectroscopic coating(VIS/NIR) can withstand higher power than standard film substrate polarizer coating. It can be used on window substrate and also laser cavity.

Angle of Incidence: Brewster’s Angle Reflectance: Rs ≥ 99%
Transmittance: Tp ≥ 95% Extinction Ratio: Tp / Ts ≥100:1

Coating Workshop

Boxin has been continuously upgrading its coating facilities. At present, Boxin has 10 sets of advanced local and foreign made coating machines and customize various optical coating layers according to customer inquiries.

Film inspection

Boxin has established a completed coating inspection system, equipped with Hitachi u-4100 , FTIR-920 IR, american-made PE-Lambda 950 spectrometers and other advanced coating inspecting equipment, and also, Boxin independently developed the Laser-induced Damage Threshold machine to accurately testing LIDT coatings, so as to provide customers with high-quality LIDT coatings.
