The beam splitter is composed of two precisely aligned right-angle prisms bonded together, featuring a specific interference coating. This structure minimizes wavefront distortion, ensuring high-quality optical performance.
High Reflectivity and Transmission Control: A beam splitter cube is a medium that partially reflects and partially transmits light, typically controlled by coatings to achieve the optimal interference effect. This design allows photons to scatter with a certain amplitude while also transmitting directly with a certain amplitude, thereby achieving beam splitting.
Minimal Wavefront Distortion: The cube beam splitter from the professional optical prism suppliers is composed of a pair of precisely aligned right-angle prisms that are carefully bonded together to minimize wavefront distortion. This design ensures that the beam maintains high quality during transmission.
Multiple Application Scenarios: Beam splitter cubes are widely used in various scientific and engineering fields, including quantum optics, optical instruments, and optical communications. They can split a beam into two paths for applications such as interferometry and spectral analysis.
Compatibility with Mounts and Adjustment Frames: Cube beam splitter mounts are designed to install 0.5-inch or 1-inch cube beam splitters into optical adjustment frames, ensuring that the transmitted beam can pass through the aperture, facilitating use in various optical systems.
With these features, the beam splitter cube has become an indispensable component in the field of optics, providing crucial support for scientific research and technological applications.

The working principle of a beam splitter cube is based on the partial reflection and partial transmission properties of light. It is typically composed of two BK7 glass prisms, with a beam-splitting coating applied to the prism surfaces. This coating allows the incident light to be divided into reflected and transmitted parts according to a specific ratio. This design enables a portion of the light beam to be reflected while the other portion is transmitted, thereby achieving beam splitting.
With these features, the beam splitter cube has become an essential component in the field of optics, providing crucial support for scientific research and technological applications.
