Wire Grid Polarizers

â–  Wire Grid Polarizers - These wire grid polarizers cover wavelengthsfrom 2µm to 30µm. Wire grid polarizers are made from CalciumFluoride (CaF
2 ), Barium Fluoride (BaF
2 ), Zinc Selenide (ZnSe) andKRS-5 for performance far into the infrared.

Glan-Taylor & Double Glan-Taylor Polarizers

â–  Calcite & YVO
4 Glan-Taylor Polarizers - Calcite Glan-Taylor& Glan-Laser Polarizers are broadband, high extinction ratio, polarizers(100,000:1). Glan-Laser polarizers are Glan-Taylor polarizers that havebeen designed to have an extremely high damage threshold (500MW/cm
2 10ns pulses @ l = 1.06µm). YVO
4 Glan-Taylor Polarizershave an extremely high damage threshold. These are ideal for Q-Switched Nd:YAG and Nd:YVO
4 Lasers.

Wollaston & Rochon Prism Polarizers

â–  Wollaston Prism Polarizers - Offer the widest deviation of beamdisplacing polarizers. Since the output deviation is chromatic, Wollastonprisms have been used in spectrometers and polarization analyzers. Both output beams are deviated symmetrically to within 1°.
â–  Rochon Prism Polarizers - Designed to deviate one polarization whileallowing the other to pass. Our Rochon prism is made from MgF
2 allowing operation from UV (140nm) to IR (7µm). Rochon prisms areoften used for wideband spectrometers and beam splitter applications.

Glan-Thompson & Polarizers

â–  Glan-Thompson Polarizers - Glan Thompson polarizers providethe widest field of view of the calcite polarizers while maintaining a highextinction ratio. In applications where the input angle cannot be well controlled these prisms are the ideal solution.

Z-Cut Quartz & Beam Displacers

â–  Z-Cut Quartz - These Z-cut quartz crystals rotate linearly polarized lightas a function of wavelength and the length of the crystal. Both 45º and90º rotation are offered.
â–  Beam Displacers - Beam Displacers are used to Separate an Input Beaminto Two Orthogonally polarized Output Beams

Dichroic Sheet Polarizers,Depolarizers & Lithium Niobate

â–  YV0
4 Walk-off Wedges - YVO
4 Walk-off wedges are designed to beused in the production of OEMisolators by combining two wedges witha Faraday rotator.
â–  Dichroic Sheet Polarizers - Dichroic Sheet Polarizers deliverperformance without the price. Polarization with 1,000:1 extinction ratiois maintained in the range of operation.
â–  Beamsplitter Polarizers - These use a coating rather than birefringentmaterials to split the S & P polarization. Although they work over anarrower range and lower extinction ratio than birefringent polarizers, they have the advantage of dividing S & P with a 90°deviation.
â–  Depolarizing Prisms - Depolarizers are used where linearly polarizedlight is undesirable such as with polarization sensitive devices. Thedepolarizer converts the polarized input into a pseudo-randomlypolarized output.
â–  Lithium Niobate Wafers - Lithium Niobate has excellent electro-opticand non-linear optical properties. These Stoichiometric Lithium Niobatewafers are available in x-cut and z-cut configurations.
