Wollaston Crystal Polarizing Prism WP10
Wollaston crystal polarizers join two birefringent right-angle prisms at their hypotenuses. Mutually perpendicular optical axes, both perpendicular to propagation, create an abrupt axis change at the interface and symmetric o/e deflection. Outputs are orthogonal, equally bright, strongly separated linear polarizations, both usable simultaneously, each with extinction ratio >100,000:1. Applications include polarimetry and spectroscopy. JCOPTIX offers calcite with chemical cement and α-BBO with optical contact bonding for higher damage threshold and high power. Contact technical support for other substrates, coatings, or sizes. Standard SM1 external housing threads fit SM1 mounts such as MMR-1T. A proprietary rubber buffer at the SM1 thread base aligns polarization to a chosen rotation-mount angle. 1. Screw the prism fully into the mount's SM1 thread and lock rotation if required. 2. Compare the white polarization mark with the desired 0° or 90° scale. 3. Continue turning the protruding housing gently until aligned, with about 60° available adjustment.
