With the development of science and technology, the beam splitter prism not only becomes an indispensable tool in basic optical experiments, but also plays an important role in the fields of modern instrument and equipment, communication, astronomical observation and the like. The beam-splitting prism frame is an indispensable key component in an optical system, and provides a guarantee for efficient operation of optical experiments and instruments by ensuring the stability and the accurate angle adjustment of the beam-splitting prism.
