Please contact us for
your applications and crystals of other sizes. We can provide large BBO crystals
with the size up
to 20x20x40mm or
ultrathin crystals
with the thickness down to 10
µm.

Coatings
1.Protective coating (P-coating): This is single-layer MgF2 coating protecting
polished surface of BBO from fogging due to
ambient moisture. The protective coating can also partially reduces reflection from polished surface
at a certain wavelength range.
2. Anti-reflective coatings (AR coatings): These are multi-layer dielectric coatings. Single-band, dual-band
or broad-band
AR coatings on BBO surfaces are available upon request.
Mounts
For customer convenience the crystals can be mounted
free of charge in a
standard 1" anodized aluminum (Al) mount. The mounted crystals may be further
mounted in a conventional 1" mirror mount to be angle tuned for phase
matching ( mirror mounts and posts are not included ).
