By using Chinese brand BBO crystals.
For spatial compensation of the angle dependent phase from a SPDC crystal.
Matched to the SPDC crystal with the same material and the same cut angle.
Better Wavefront distortion: λ/8@633nm.
With AR@405/810nm coating for 405nm pumped SPDC crystals.
Other coating specification are available.
