Beamsplitter Prism
A beam-splitting prism is a common optical element that separates light according to color. It is used in laboratories, medicine, and industry to decompose light into spectra of different wavelengths for spectral analysis, color measurement, and optical-instrument calibration. It is made from high-quality optical glass with precisely polished and reflectively coated surfaces. Its shape is generally triangular, with one edge called the base and the other two used to separate light. Specific geometries and glass refractive indices enable separation or combination of light within a specified wavelength range. In practical applications, beam-splitting prisms work with other optical components such as light sources, detectors, and gratings to measure and analyze light properties. Research applications include analysis of laser frequency, spectral composition, and polarization direction. Medical diagnostic applications include detecting and analyzing chemical components in blood, urine, and other biological samples. They are also used to calibrate optical instruments. The prism first decomposes light from a source into a series of specific wavelengths, which are then measured by a detector. This ensures accurate, consistent instrument response to different wavelengths, making the prism important in optical metrology, instrument manufacturing, and quality control. Overall, beam-splitting prisms separate light by color and have broad laboratory, medical, and industrial uses, supporting research, diagnosis, and calibration. High-quality materials and precise fabrication make them indispensable optical tools.

PBS beamsplitter prism Prisms 100optics
Material [Shared by the standard/high-precision columns; Original cell colspan2]: N-BK7.Fused Silica,N-SF11,or depend on request Clear Aperture [Standard specification]: ≥85 % Dimension Tolerance [Standard specification]: ±0.1 mm
A polarizing beamsplitter separates incident unpolarized light into two orthogonal linearly polarized beams. P-polarized light is fully transmitted, while S-polarized light is reflected at 45 degrees and exits at 90 degrees to the P beam. Made from a pair of cemented high-precision right-angle prisms, with a polarizing beamsplitter dielectric coating on the hypotenuse of one prism.

Triangular Prism Prisms 100optics
Material: K9 or ZF glass, etc. Dimensional Tolerance [Two original parallel options without grade distinctions]: ±0.2，±0.1 Surface Quality: 60 / 40
Prisms turn and displace light at specified angles and can adjust image orientation. Their shape and function depend on their interaction with light. Incident light may reflect from one or more surfaces before exiting, or refract while passing through the substrate. Baijing offers forms including triangular prisms, pentaprisms, Dove prisms, Powell prisms, roof prisms, and corner cubes.
