Convention Polarizing Cube Beamsplitters (PBS)

Polarizing Cube Beamsplitters (PBS) split randomly polarized beams into two orthogonal,linearly,polarized components-S-polarized light is reflected at a 90deg while P-polarized light is transmitted.
Each beamsplitter consists of a pair of precision high tolerance right angle prisms. cemented together with a dielectric coating on the hypotenuse of one of prisms.
Visible (450 - 650 nm) and NIR (1200-1600nm) wavelength is available.
1000:1 Extinction Ratio for Single Wavelength PBS.
500:1 Extinction Ratio for Broadband PBS.

What is a Polarizing Cube Beamsplitters ?

Polarizing Cube Beamsplitters (Brief PBS) are formed from two right angle prisms permanently cemented (UV Glue) together. The hypotenuse is coated with the polarization sensitive dielectric coating designed to separate an incident unpolarized beam into Orthogonal S and P polarization components.one of which will be reflected and the other will be transmitted.

What is the difference between a regular and a Polarizing Cube Beamsplitters ?

While a regular beam splitter splits the beam 50/50, a polarizing beam splitter typically divides it in a 95/5 ratio. In addition to the cube beam splitter, there is also the plate beam splitter that is commonly employed to produce cost-effective non-polarized beam splitters.

What is the transmission( p-pol and s-pol ) of Polarizing Cube Beamsplitters ?

The transmittance curve of Polarizing Cube Beamsplitters at 1200-1600 nm.webp

What is polarizing and non-Polarizing Cube Beamsplitters ?

Incident light is split into two or more beams of the same wavelength using beamsplitters. The exiting beams are classified based on their optical power (non-polarizing) or polarization states (polarizing). In non-Polarizing Cube Beamsplitters, the amount of light in the reflected arm versus the amount of light in the transmitted arm is specified as the splitting ratio. On the other hand, the extinction ratio, which is the ratio of P-polarized light to S-polarized light in the transmitted arm, specifies polarizing beamsplitters.

How are Polarizing Cube Beamsplitters made ?

Polarizing Cube Beamsplitters are comprised of two prisms positioned at right angles. One of these prisms includes a dielectric coating evaporated on the intermediate hypotenuse surface.

How much does the Polarizing Cube Beamsplitters cost?

The price of Polarizing Cube Beamsplitters depends on factors such as its size, wave band range and quantity. Generally speaking, the price ranges from tens of dollars to hundreds of dollars.

How do I clean and maintain the Polarizing Cube Beamsplitters?

The Polarizing Cube Beamsplitters requires regular cleaning and maintenance, which can be cleaned with pure ethanol, avoiding the use of organic solvents and strong acid and alkali solutions.

How many types of Polarizing Cube Beamsplitters ?

One that uses cemented method for Convention Polarizing Cube Beamsplitters and the other that uses optical Bonding technique for High Power Polarizing Cube Beamsplitters.
