Optical part: beam splitting plate
Beam splitting plate (18X18X1.5mm)
1. Beam splitting coating @850 on S1 surface. T/R=30/70 for both polarizations
2. Both the transmittance and reflectivity for s and p polairzations have less than 3% difference
3. Angle of incidence (AOI) is 45 degrees
4. AR coating (R<1%)@850nm on S2 surface.
5. Coatings pass MIL-C-675C and pass type adhesion test
6. Parallelism between S1 and S2 is less than 1 arc minutes
