The Non-Polarizing Cube Beam Splitter (NPBS) consists of right-angle prisms with the metallic-dielectric coating on one of the prims' hypotenuse. The polarization state of the output beam is the same because of the low polarization dependence of the metallic-dielectric coating.


CRYSMIT‘s Non-Polarizing Cube Beamsplitters for wavelengths in the visible (400 - 700 nm) and infrared (1200 - 1600 nm) ranges, all of which are insensitive to polarization. Beamsplitter cubes are available with split ratios of 30:70, 50:50, or 70:30, and in sizes of 10 mm, 20 mm, and 25.4 mm.

What is a Non-Polarizing Cube Beamsplitters ?

The Non-Polarizing Cube Beam Splitter (NPBS) consists of right-angle prisms with the metallic-dielectric coating on one of the prims' hypotenuse. The polarization state of the output beam is the same because of the low polarization dependence of the metallic-dielectric coating.


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 Non-Polarizing Cube Beamsplitters made ?

Polarizing beam splitter cubes are comprised of two prisms positioned at right angles.One of these prisms includes a Non-polarizing dielectric coating evaporated on the intermediate hypotenuse surface.


How much does the Non-Polarizing Cube Beamsplitters cost ?

The price of Non-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 Non-Polarizing Cube Beamsplitters ?

The Non-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.
