Rochon Polarizers
Materials: α-BBO, Quartz, MgF2 or YVO4 crystal.
Optically contacted structure. No optical cement in optical path.
High extinction ratio (>100,000:1) over an extremely
large range of wavelength.
High UV transmission.
O-ray passes through undeviated, e-ray deviated.
Large separation angle between the o- and e-rays (see "Tech Info").
Custom angles are available.
