Wollaston Prisms
-
Evenly splits both polarizations into two divergent beams
-
Available with 5, 10, 15 and 20 degree beam separation
-
Mounted in a metal cell for convenience and protection
-
Extinction ratio of 1x10-5
-
Handles power levels to 1W/cm2 CW, 5W/cm2 pulsed
Wollaston Prisms split an incoming beam into two separate output beams of orthogonal polarization. The two beams have an angular separation which can be either 5, 10, 15 or 20 degrees and which is approximately symmetrical about the optical axis.
