The polarization splitter prism is plated with a multilayer film structure on the inclined surface of the right Angle prism, and then glued into a cube structure. By taking advantage of the property that the transmission rate of P-polarized light is 1 and that of S-polarized light is less than 1 when the light incident at Brewster Angle, the P polarization component can be completely penetrated after the light passes through the multilayer film structure at Brewster Angle for many times. And most of the S polarization component is reflected. Note: Specific bands and extinction ratios can be customized according to customer requirements.
POLARIZING BEAM SPLITTER（PBS-HP）
The High Power PBS uses a special Optical Contacted technology, that is, optical bonding technology, its biggest advantage is that the mechanical strength after bonding is larger, the damage threshold is higher, which also means that the bonded product can be cut, polished, coated, coated and bonded, etc., without considering the impact of high temperature and high laser power on itself. Because there is no glue inside the High-Power PBS, the bonding face has almost no absorption of the laser, and the bonding surface will not be damaged due to high temperature.
NON POLARIZING BEAM SPLITTER（NPBS）
NON-POLARIZING BEAM SPLITTER (NPBS) is made of glass material, through the beamsplitting membrane of the beamsplitting medium to achieve the effect of depolarization, NPBS spectral ratio and the polarization state of the incident light is independent, can make the incident light of any polarization state into two beams of light output close to 1:1, the polarization state of the outgoing light is approximately the same as the incident light.
Brewster windows are commonly used for polarization in laser cavities. When placed at the Brewster angle, the P-polarized component of the beam will be completely transmitted, while the S-polarized component will be partially reflected, thus increasing the loss of the S-component in the cavity.
The natural light becomes polarized light, separating or combining the s polarization and p polarization components at 45° incidence angles. So that only light waves in a particular direction can pass through. By controlling the direction of light polarization to produce a specific effect. They are designed for use in high energy lasers. Polaroids made by UVFS have a high laser damage threshold.
Glan Taylor Polarizercontain a variety of materials, including Calcite crystals, A-BBO crystals, YVO4 crystals, . Glan Taylor Polarizer are compact and shorter in length than Glan Laser Polarizer, making them suitable for high polarization applications at low to medium power. It can make the input unpolarized beam into a pure polarized light, and is often used as a bias or bias detector for optical path systems.
We offer a wide range of materials including Calcite crystals, A-BBO crystals, YVO4 crystals .The Glan Laser Polarizer is a Glan Polarizer specially used in high energy lasers with two escape Windows on the side. The prism has a very high laser damage threshold, and the extinction ratio is also higher than the ordinary Glantler prism. After the beam passes through the prism, it transmits pure P-polarized light, and the side escape window emits pure S-polarized light and a small part of P-polarized light, which can be used for occasions where both polarizations are needed or for the combination of two polarized light.
The Glan-Thompson prism is made of two crystals bonded together. It has a very large field of view while maintaining a high extinction ratio. Its wavelength range is wide; the a-BBO material Glan-Thompson prism operates in the 200-900nm range, and the Calcite material Glan-Thompson prism operates in the 350-2300nm range. It is an ideal wide-band, large-field-of-view polarizing device, often used as a polarizer in spectral analysis systems.
We can provide Wollaston prisms in a variety of materials, including Calcite crystals, A-BBO crystals, quartz crystals, YVO4 crystals, etc. Wollaston prism is made of two crystals bonded or photoadhesive, which can change the incident unpolarized light into two orthogonal polarized light beams. It can work in a wide band range, and the field of view is relatively large. Unlike other polarizers, both of Wollaston's output beams are highly polarized, with extinction ratios greater than 10,000:1 or 100,000:1. The beam separation Angle can be customized according to customer requirements, and the beam splitting output can be achieved at any Angle from 0 to 25°. The material of the prism can be selected according to the size of the beam splitting Angle and the band used.
