Wollaston Polarizers
• Multiple Polarization Materials Available
• UV to IR Ranges Off ered
• Large Deviation of Ordinary and
Extraordinary Rays
Wollaston Polarizers consist of two birefringent right
angle prisms cemented together, such that their optical
axes are perpendicular. As light passes through the
polarizer, a symmetric deviation between the ordinary
and extraordinary beams is created. The resulting
beams are of orthogonal linear polarization states and
have equal intensity and a large angular deviation. Users
have access to both the ordinary and extraordinary
rays, making them ideal for laboratory experiments.

• Multiple Polarization Materials Available
• Ordinary Rays Pass Through Undeviated
• Extraordinary Rays Deviate
Rochon Polarizers consist of two birefringent
material prisms in optical contact with one another.
The ordinary and extraordinary rays remain
collinear through the fi rst prism. Upon entering the
second prism, the ordinary rays do not experience
a change in the refractive index and pass through
the prism without deviation, while the extraordinary
rays refract at the interface.

Glan-Type Polarizers
• Broadband Performance from 200 - 2300nm
• High Extinction Ratios up to 200,000:1
• High Laser Damage Thresholds up to 5 J/cm2 @ 1064nm
Glan-Type Polarizers are mounted, polarizing prisms used in applications that require broad spectral ranges,
high extinction ratios, or high polarization purities. Glan-Taylor Polarizers are medium-power, air-spaced UV
to NIR polarizers that transmit the extraordinary beam. The ordinary beam is then refl ected and absorbed by
black glass plates that have been cemented to the prism. Glan-Laser Polarizers are similar to Glan-Taylor, but
are designed for higher power applications. Glan-Laser Polarizers utilize an advanced polishing technique for
minimizing surface scatter and feature two escape windows for passing the high power rejected light. Glan-
Thompson Polarizers are low power polarizers that are ideal for UV, visible, or NIR applications, feature a
cemented design, and transmit the extraordinary beam while absorbing the refl ected ordinary beam.
