UV Polarizers (ROCHON, LOW POWER ONLY)

We manufacture the classical Rochon Polarizers in crystal quartz and MgF2. Low power only! Damage threshold is complex. Please Inquire.

SPECIAL NOTICE
Significant power limitations must be observed with PVR and PUR models. Do not use with unexpanded laser beams, as power density (beam cross-sectional area) can cause de-contacting of polarizer prisms. See High Power UV Polarizers below.

SPECIAL NOTICE
Polarized input beams can only be used with PVR polarizers. Unpolarized input beams can be used with either PVR or PUR Polarizers.

Transmittance	85 - 91% (N-type) ~ 71% (T-type)
