Polarizing Beamsplitter Prisms

Depolarization splitting prism is an optical element, which coats multilayer interference film on the inclined surface of right-angle prism, gluing with another right-angle prism, forming a cube structure to let through incident P-polarized light and reflect S-polarized light. It separates the parallel and vertical polarization of a beam of light, and the transmittance ratio of P light to S light is greater than 900. It has the advantages of low stress, high spectral ratio, good imaging quality and small beam deflection angle.

Polarizing Beamsplitter Prisms

Features

The polarizing beam splitter prism is an optical element that coats a multi-layer interference film on the inclined surface of a right angle prism, and is glued with another right angle prism to form a cube structure, thereby allowing the incident P-polarized light to pass through and S-polarized light to reflect. The parallel polarization and vertical polarization of a beam of light are separated, and the ratio of the transmittance of P light to S light is greater than 900. It has the advantages of low stress, high beam splitting ratio, good imaging quality and small beam deflection angle.

Smart Recognition Filter

Neutral density spectroscopic film is also known as attenuator, ND mirror. It identically and uniformly reduces light of different wavelengths, effectively reduces light, and does not change the color of the original object. Therefore, it can truly reproduce the original color of the object. It has the advantages of wide band attenuation rate, accurate attenuation, insensitivity to incident angle and polarization state, solid film layer, scratch resistance and strong hydrophobicity.
