Wollaston Polarizers

Materials: Calcite, α-BBO, Quartz, or YVO4 crystal.
Typical structure: Optically cemented structure,
Optically contacted (cement-free in the optical path) structure aslo available
with materials α-BBO and Quartz.
High UV transmission down to 200 nm.
High extinction ratio (>100,000:1) over an extremely
large range of wavelength.
Large separation angle between the o- and e-rays (see "Tech Info").
Custom angles are available.
