Unless the coating is specified, PDB (a-BBO) is coated with single-layer MgF2 protective coating (P-coating) to prevent moisture from the polished faces, PDC (calcite) and PDY (YVO4) are uncoated.
Input and output faces can be AR coated with R<0.25% at the specified central wavelength. For the inquiry, please specify the coating and append to the part number, e.g.PDC1040-AR800 for the calcite beam displacer with the AR coating @ 800 nm.
Common AR coatings:
α-BBO: 355, 400, 532, 775, 800, 1030, 1064, 1550 nm, and dual AR@800/400n m, 1030/515 nm, 1064/532 nm, 1550/755 nm
Calcite: 775, 800, 820, 1064, and 1550 nm
YVO4: 1064 and 1550 nm
The displacers are mounted in an OD 1" anodized aluminum (Al) mount. Unmounted displacers or custom mounts are available upon request.
