alpha-BBO & Calcite Glan Thompson Polarizer

Glan Thompson Polarizer is made of two α-BBO or calcite prisms cemented together. It has a wavelength from 200nm to 2300nm. α-BBO polarizer can be used from about 200nm to 1100nm, and calcite polarizer can be used from 350nm to 2300nm.   This type polarizer has higher extinction ratio than air spaced polarizer. And it has the widest field angle of any design. For example, α-BBO Glan Thompson Polarizer has an angular field lager than 15 degree.

Glan Taylor Polarizer alpha-BBO & Calcite material Glan Taylor Polarizer
alpha-BBO & Calcite material Glan Taylor Polarizer
Glan Taylor Polarizer is made of two same birefringence material prisms which are separated by an air space. The polarizer with on side escape window is suitable for low to medium power application. Glan Taylor Polarizer will divide an entering unpolarized beam into beam rays, one is the extraordinary that is transmitted through the other side, and another is the ordinary ray that is totally internally reflected absorbed.

Optical alpha-BBO & YVO4 Rochon Polarizer
Rochon Polarizer is the earliest polarizer, which is made of two birefringence material prisms that are cemented together. This type polarizer separates incident beam into ordinary ray and extra-ordinary ray like Wollaston Polarizer, but the extra-ordinary ray is straight transmitted through, while ordinary is transmitted with a deviation angle.

Waveplate Waveplate
Waveplate
Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices. The difference in velocities gives rise to a phase difference when the two beams recombine. In the case of an incident linearly polarized beam this is given by a=2pi*d(ne-no)/l (a-phase difference; d-thickness of waveplate; ne,no-refractive indices of extraordinary and ordinary rays respectively; l-wavelength). At any specific wavelength the phase difference is governed by the thickness of the retarder. Transmission range:330nm-2100nm Thermal Expansion Coefficient:7.5x10-6/K .Density:2.51g/cm3  Half Waveplate The thickness of a half waveplate is such that the phase difference is l/2-wavelength (true-zero order) or some multiple of l/2-wavelength (multiple order).  A linearly polarized beam incident on a half waveplate emerges as a linearly polarized beam but rotates such that its angle to the optical axis is twice that of the incident beam. Therefore, half waveplates can be used as continuously adjustable polarization rotators. Half waveplates are used in rotating the plane of polarization, electro-optic modulation and as a variable ratio beamsplitter when used in conjunction with a polarization cube. Quarter Waveplate The thickness of the quarter waveplate is such that the phase difference is l/4 wavelength (true-zero order) or some multiple of l/4 wavelength (multiple order). If the angle q (between the electric field vector of the incident linearly polarized beam and the retarder principal plane) of the quarter waveplate is 45, the emergent beam is circularly polarized. When a quarter waveplate is double passed, i.e. by mirror reflection, it acts as a half waveplate and rotates the plane of polarization to a certain angle. Quarter waveplates are used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwanted reflection and optical isolation.
