Polarizing Beam splitters Cube

Polarizing Beam Splitter, when the incident angle meets the Brewster angle condition and the reflectivity of polarized light P is 0, controls the film layer so that the reflectivity of polarized light s is close to 1 and the transmittance of polarized light p is close to 1. When a beam of light enters the film layer in the air, it is difficult to reach the Brewster angle condition due to the relatively small refractive index of the air. Therefore, the film layer must be sealed inside a glued prism.

Compared with a splitter, the reflected and transmitted light paths of a splitter prism are equal. When transmitting light, the splitter prism does not have the effect of light deviation, so there is no problem of beam translation, ghost images, or interference. Used for spectroscopy and imaging. There is no need for long-term calibration when incident at a 45 ° angle. The P-component of the incident light is completely transmitted, while the S-component of the incoming light is reflected in a direction perpendicular to 90 °.

It is composed of two ultraviolet fused silica right angle prisms. The dielectric spectroscope can reflect S polarized light and transmit P polarized light. The surrounding area of the cube can serve as the incident plane and separate P-polarized light and S-polarized light. To achieve optimal polarization performance, it is recommended that the incident light be incident from the right angle edge of a prism coated with a polarization splitter film (a prism with a black dot at the top indicates that its inclined plane is coated with a dielectric polarization splitter film). The extinction ratio of the laser linearly polarized beam splitting cube Tp: Ts>3000:1, and all four pass surfaces are coated with a V-shaped antireflection film designed for single wavelength, with a reflectivity of less than 0.25% @ design wavelength. LBTEK offers 10 design wavelengths to choose from, including 405 nm, 532 nm, 633 nm, 780 nm, 808 nm, 830 nm, 850 nm, 1030 nm, 1064 nm, and 1550 nm.

The prism with black dots on the top of the polarizing beam splitter cube indicates that its inclined surface is coated with a dielectric polarizing beam splitter film, which can reflect S-polarized light and transmit P-polarized light. All around can serve as the incident plane and separate P-polarized light and S-polarized light. To achieve optimal polarization performance, it is recommended that the incident light be incident from the right angle edge of a prism coated with a polarization splitter film.
