Polarization Beamsplitter Cubes are constructed by cemented two right angle prisms, the hypotenuse of one prism is coated with polarization dielectric coating.
When used with normal incident, un-polarized light, the incident beam is separated into two polarized beams, p-polarized component is passed straight through, s-polarized component is reflected out at 90deg.

1.1、What is a Polarizing Beamsplitter Cube?
A polarizing beamsplitter cube consists of two right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multi layer dielectric coating. When circularly polarized or natural light enters the cube vertically, it separated into two linearly polarized beams. The transmitted beam is P-polarized while the reflected beam is S-polarized. And when a linearly polarized light comes in, it similarly divided into two beams. But the energy ratio of the two outgoing beams depends on the polarization of the incident beam. Polarizing beamsplitter cubes are available for many laser wavelengths and broadband ranges.
1.2、How does a polarizing beamsplitter Cube work?
Polarizing Beamsplitter is designed to split unpolarized light at a specific Reflection/Transmission (R/T) ratio with unspecified polarization tendencies.
Polarizing beamsplitters are designed to split light into reflected S-polarized and transmitted P-polarized beams.
1.3、What is a Polarizing beamsplitter Cube used for?
Beamsplitter is also a kind of filter, it is used to split or combine laser beam. However Polarization BeamSplitters are used to split or combine two perpendicular polarization laser beam. The performance of beam splitter depends on the coating specifications. They are common components in laser or illumination systems. Also ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation. Light can be split by percentage of overall intensity, wavelength, or polarization state.
To select a suitable beamsplitter, you need to consider the type, coating, transmission range and damage threshold.

Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50%, etc.

Our beamsplitter plates can be used in high power laser system. When using beamsplitter plates, it is important to make it in mind that the two partial beams travel in different optical paths. The optical paths depend on the incident angle and the thickness of plates.

Color glass changed the spectral properties of optical radiation. They therefore allow scientific experiments and industrial applications where that change is necessary. You can combine color glass filters together to change the bandpass or to increase the attenuation. Color glass change the spectral properties of optical radiation.
