Foctek Photonics, Inc. Datasheets for Optical Polarizers

Optical polarizers are optical devices that can transform unpolarized or natural light into polarized light, usually by the selective transmission of polarized rays.

Product Name Notes
Broadband Glan Thompson Polarizer is made of two a-BBO prisms cemented together. Unlike other types of a-BBO polarizer and Calcite Polarizer which are used from about 200 nm to 900...
Dual wavelength waveplate is a multiple waveplate that provide a specific retardance at two different wavelengths, it's particularly useful when used in conjunction with other polarization sensitive components to separate...
FOCtek specially designed a high transmission Glan Laser Polarizer for online_ordering which requires high transmission. The specially designed polarizer is based on the Brewster Cut crystal, which can improve the...
Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and...
Glan Taylor prism polarizer is made of two same birefringent material prisms that are assembled with an air space. It has a length to aperture ratio less than 1.0 makes...
Glan Thompson polarizer is made of two calcite prisms or a -BBO prisms cemented together. Two types of Glan Thompsons are available. One is the standard form and the other...
Polarization rotators offer 45deg or 90deg rotation at a number of common laser wavelength, the optical axis in a polarization rotator is perpendicular to the polished face of the optic.
Rochon polarizer is one of the earliest designs, which is made of two birefringent material prisms cemented together. Both ordinary and extraordinary beams propagate collinearly down the optic axis in...
The low(multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However,...
The Polarization Beam Combiner is made of two pieces YVO4 Prism or Calcite Prism. The Calcite Polarization combiner can be with 45° or 90° of two polarization Beam Input. Please...
The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performances than multiple order waveplates, it has...
This DAQ series of depolarizers is an improved Quartz Lyot Depolarizer, which consists of two quartz crystal wedges with their optic axes lying in the plane of the plates, and...
This DQW series of depolarizer consists of a crystalline quartz wedge together with a compensating fused silica wedge to correct the angular deviation. The optic axis of the quartz wedge...
This precision optical instrument is invaluable for the complete analysis of polarized light. There are two models available-Model BSC 100 fabricated from synthetic crystal quartz which spans from 190-1600nm and...
This type of zero order waveplate is constructed of a true zero order waveplate and a BK7 substrate. As the waveplate is very thin and easy to be damaged, the...
This useful instrument introduces a variable rotation between 0° and 90° to an input plane polarized beam. The rotation angle is controlled by a manually driven precision micrometer. Calibration scales...
Unlike standard waveplates, Achromatic Waveplates, AWP, provide a constant phase shift independent of the wavelength of light that is used. This wavelength independence is achieved by using two different crystalline...
Wollaston polarizer is made of two birefringent material prisms that are cemented together. The deviations of the ordinary and extraordinary beams are nearly symmetrical about the input beam axis, so...
