Polarizing Plate Beam Splitter Product Attributes
Polarizing Plate Beam Splitter (PBS) belongs to Polarization Optics, as a kind of core Optical Elements of Laser Components, is including 45 degree Polarizing Plate Beamsplitter with UV Fused Silica and 56.3 degree Polarizing Plate Beamsplitter with BK7 material or UV Fused Silica. The front surface of Coupletechs' Polarizing Plate Beamsplitter has a narrow band splitter that is used for a variety of laser wavelengths. And need to Brewster Angle 56.3 degree of incidence of the traditional polarization splitting different lens, or the Electro-optic Components requires a 45 ° Angle of incidence, and therefore easier to install. Although the Angle can be adjusted, this can result in the reduction of the achievable extinction ratio. Polarizing Plate Beamsplitter is composed of ultraviolet quartz glass or BK7 Material. These beam splitter mirrors the s polarized light at a 45 degree Angle, p polarized light transmission. Beam, in fact, these points can be regarded as 45 ° high reflector, the two reflection band to compensate each other, makes the high p polarization component, s high polarization component reverse at the same time. As well as 56.3 degree. They are all made up of optical elements. The hard coating on the polarizable plate splitter has a higher damage threshold than the ordinary coating. For applications requiring high extinction ratio, high transmittance and high damage threshold, these splitter mirrors are more suitable than polarized beam cubes. The characteristics of polarizing spectroscope are separated from beam and P beam, and the Angle of brewster Angle is applied to high power applications, through lead-free certification. The edges of each circular plate splitter are engraved with a product model and an arrow pointing to a wedge surface that is coated with a membrane.

Bogaolaser
Configure: 1×2 Grade: Class A Central Wavelength [optional (Optional)]: 400-2000 optional (Optional)
Our splitters can be configured with different center wavelengths and fiber types to achieve customer-specified splitting ratios. They use fiber-fusion technology to divide power from one fiber equally or proportionally among outputs, or to combine light from multiple fibers into one fiber in reverse operation, with high transmission efficiency. Available splitting/coupling ratios include 50:50, 10:90, 15:85 and 1:99, with selectable wavelengths from 400-2000nm. Customization includes coupling structures such as 1x2, 1x4 and 2x2, power, wavelength, coupling ratio and connectors.

HPBS-High-Power Polarizing Beamsplitter Cube
Beam Splitters
Sunday-optics
Material: JGS1 Dimensions: 2、3、5、10、12.5、12.7、18、20、25、25.4、38.1、50.8、100mm Tolerance: -0.2 mm
The high-power polarizing beamsplitter cube comprises two precision UV-fused-silica right-angle prisms with special coatings on their hypotenuse faces, bonded together. It splits arbitrary incident light into perpendicular linearly polarized beams: all P polarization transmits along the incident direction, while all S polarization reflects perpendicularly. Custom Tp:Ts ratios greater than 1000:1, 2000:1 or 5000:1 are available. Special bonding replaces conventional optical cementing to meet laser and cutting requirements. Extremely high temperature resistance and strong laser resistance are key features. Typical laser wavelengths are 266, 355, 450, 532, 633, 760, 767, 780, 808, 905, 1064 and 1550 nm. Laser damage threshold reaches 15J/cm2@1064nm, 20ns, 20HZ.
