Material	BK7, UV FS
Surface quality	40-20 scratch & dig (MIL-PRF-13830B)
Clear aperture	80% of the face size
Flatness	λ/4 @ 633 nm
Beam deviation	< 3 arcmin
Dimensions tolerance	±0.5 mm
Reflectance/Transmittance	50%/ 50% with tolerance ±5% at designed wavelengths

Two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face
Reflectance/Transmittance is 50 / 50 % with tolerance of +/-5% at designed wavelengths

All dielectric coatings of fixed ratio laser beamsplitters are optimized to be insensitive to split only s- or only p-polarization or only unpolarized light (R = (R_S+R_P)/2 and T = (T_S+T_P)/2) at designed wavelengths.
