Precision Linear Polarizers

We manufacture Precision Linear Polarizers using dichroic sheet polarizer material laminated between high quality glass substrates. For visible wavelength polarizers, this construction produces a peak-to-valley transmitted wavefront distortion of less than λ/5. Various polarizer materials are used to cover wavelengths within 320 and 2000 nm. Both visible and near infrared polarizers are supplied with a high-efficiency, broadband antireflection (AR) coating; single-layer AR coatings are optional on our ultraviolet polarizers. Both mounted and unmounted Precision Linear Polarizers are offered as standard products. To facilitate use, our Precision Linear Polarizers have the transmission axis marked on the part.

Ice Cube - Wire Grid Polarizing Beam Splitter

KEY FEATURES

This polarizing beam splitter (PBS) cube is optimized for use over a wide range of acceptance angles while maintaining color uniformity and image contrast in the visible wavelength ranges. The ICE Cube allows compact optical designs with reduced optical paths. Engineers are now able to design smaller systems while maintaining excellent optical performance. The ICE Cube polarizer performance exceeds that for the commonly used thin film MacNeille cubes in both acceptable wavelength range and angle of incidence range while providing more than twice the contrast ratio in the transmitted beam for most wavelengths.

The ICE Cube is assembled by embedding our polarizing beam splitter plate between two AR coated glass prisms. These cubes are designed with Nanowire® grid structures centered on the hypotenuse of the ICE Cube. The ICE Cube PBS separates natural light into two main orthogonal, linearly polarized components; the p-polarized light which is transmitted while the  s-polarized light is reflected at a 90 degree angle. In principle, half of the incident light is reflected, and the other half is transmitted.

Laser Line Beamsplitting Polarizer

Right-angle prisms are matched in pairs to produce high quality laser line beamsplitting polarizers with superior wavefront quality in both transmission and reflection. The hypotenuse face of one prism is coated with a multilayer dielectric beamsplitting coating optimized for laser performance. Two prisms are cemented together, protecting the critical coating from performance-degrading environmental factors. Each cube separates an unpolarized incident beam into two orthogonal, linearly polarized components with negligible absorption. Following the principle of pile-of-plates polarizers, p-polarized light is transmitted with approximatley 1000:1 contrast and s-polarization is reflected with approximatley 20:1 contrast.

Broadband Beamsplitting Polarizer

For applications involving broadband or tunable wavelength sources, Sintec Optronics presents a line of Broadband Beamsplitting Polarizers covering the visible to near infrared region. These cubes offer increased utility for a range of polarization needs. As with the Laser Line Beamsplitting Polarizers, two usable polarization forms result, conveniently separated by 90°. For unpolarized input, incident light will be equally split, 50% transmitted and reflected. Varying the input polarization axis will change the split ratio. These broadband designs require well-collimated input and accurate angular alignment for optimal performance. All four entrance and exit faces are antireflection coated to minimize losses.

Dichroic Circular Polarizer

Dichroic Circular Polarizers consist of a dichroic linear polarizer and true zero-order quarterwave retarder. Precisely aligning the retarder fast axis at 45° to the linear polarization direction ensures optimum performance. True zero-order retarders are used in the assembly of our Dichroic Circular Polarizers and tight retardance tolerances contribute to the final performance.

Thin Film Polarizers

Description

High Contrast Thin Film Polarizers (TFP) are made using advanced Ion Beam Sputtering (IBS) coating technology. These thin film polarizers separate s- and p-polarization components of high energy laser beams. Due to very low losses they are perfect for intra and extra cavity usage. Because of their high damage threshold and extinction ratio (>1000:1), thin film polarizers are a good replacement for Glan laser polarizing prisms or polarizing cube beam splitters. For optimal performance, polarizers should be mounted in an appropriate holder allowing angular adjustment. We offer two types of high contrast polarizers: with higher LIDT or higher contrast values.

Polarizing Cubes for High Energy Applications

Description

Polarizing beamsplitter cubes offer several advantages over plate beamsplitters. They are easy to handle, high contrast and high extinction ratio polarizers that split a randomly polarized beam into two orthogonal linearly polarized components. These products are typically used in laser beam separation, combination and optical-isolation applications. The epoxy-free construction of the cubes enables a superior performance at high energy levels.

2. Glan Laser Polarizer

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 is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces.

3. Glan Thompson Polarizer

Glan Thompson polarizer beamsplitter cube is made of two calcite prisms cemented together. It has been arranged to permit the output of the s-polarized beam at 45° from the straight through p-polarized beam. They provide high polarization purity and high transmission in the two emerging beams. These are useful if it is required to utilize both linear polarization states. They are mounted in a rectangular metal cell and surrounded with an absorbing compound.

4. Wollaston Polarizers

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 that the Wollaston polarizing beam splitter has approximately twice the deviation of the Rochon. The separation angle exhibits chromatic dispersion, as shown in the blow. Any separation angle can be designed upon the requirement.

5. Rochon Polarizers

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 first prism under the ordinary refractive index. Upon entering the second prism the ordinary beam experiences the same refractive index and continues undeviated. The extra-ordinary beam, however, now has a lower refractive index and is refracted at the interface. The angle of refraction is further increased at the birefringent material/air exit surface. Any separation angle can be designed for specific wavelength upon the requirement.

6. Polarizating Beam Splitter

Polarizing cube beamsplitters split randomly polarized beams into two orthogonally and linearly polarized components, that is S-polarized light is reflected at a 90deg angle while P-polarized light is directly transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.

7. Depolarizer

Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change the plane polarization into a mix of polarization states by scrambling up the polarization which is to change plane polarized beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarization sensitive instrument.

The usual depolarizer can only be used at narrow band wavelength to avoid the big beam deviation. With our special design, our depolarizer can be used in a wide range of wavelength and keep the beam deviation in a acceptable range.

Usually we can get better result if we orient the input polarization state 45deg to the optical axis of the depolarizer. And also the effectiveness of the depolarizer increases with the size of the beam cross-section
