PBS Specifications:
Wavefront Distortion: < λ/4 @ 632.8 nm
Dimensions Tolerance: +/- 0.2 mm
Beam Deviation: < 3 arc minutes

Extinction Ratio*: > 300:1 for single wavelength PBS; > 150:1 for dual wavelength PBS
Damage threshold:
0.1 GW
/cm2 @1064 nm, 20 ns, 20 Hz

* The extinction ratio (ER) is the ratio of maximum to minimum transmission of a linearly polarized input. The transmission is at its maximum/minimum when the input is p-polarized/s-polarized. 



Input and output faces: Broadband AR coating with R < 0.5%.
Polarization beamsplitting coating on the 
    Transmittance of P-polarization: T> 92%,
    Reflectance of S-polarization: R> 99%.
