Fingerprint Prism

SICUBE offers ODM and OEM high-end optical components, such as the fingerprint prism. We are the leading fingerprint prisms manufacturer in China.

Optical prism is an optical device that has a triangular shape and is made of glass or quartz. This is used to deviate a beam or invert an image.

The prisms are made of materials that are transparent in optical radiation (light), in some frequency or wavelength band, and are bound by plane surfaces. An optical prism is not necessarily a strictly geometric prism. Optical prisms are subdivided into three broad classes which are sharply distinguished according to function: spectroscopic or dispersing prisms, reflecting prisms, and polarizing prisms.

Prisms are solid glass optics that are ground and polished into geometric and optically significant shapes. The angle, position, and number of surfaces help define the type and function of the prism.

The optical fingerprint prism in substantial structures consists of two ridge planes forming a right angle, one upper plane, one lower plane, and one front plane, with one finger setting.

SICUBE's high precision prisms include optical fingerprint prisms, TIR/RTIR prisms, polarizing beam splitter prisms, combination prisms, biometric prisms, AR prisms, and more. They are widely used in DLP projection, 3D cinema, fingerprint identification, 3D printing and scanning, AR display, and other fields. 


SICUBE aims to meet the needs of the Biometrics Market and cooperates with international, well-known fingerprint identification equipment companies to develop prisms for fingerprint identification. The products cover a single finger, double finger, half palm, full palm, and other industrial applications. The coating structure is optimized to improve the efficiency of identifying.
