（Scoreboard gun aiming manufacturer）Now many lenses are optical, and the blank of optical prism is the material of microscope, camera and eye lens. What is the blank of optical prism? What's the use of it?
（Scoreboard gun aiming manufacturer）Prisms are solid glass optics that are ground and polished into geometric and optical shapes. Angle, position, and number of optical flat crystals help define type and function. Sir Isaac Newton demonstrated the use of an approved prism, including dispersing a beam of white light into its component colors (below). The equipment for this application is refractometer and spectral element. As a result of this initial discovery, prisms have been used in the system to "refract" optical fibers, to "fold" the system into a smaller space, to change the direction of the image (also known as Rotationality or apposition), and to merge or split part of the reflector of the beam. These applications are very common in the use of telescopes, magnifiers, measuring instruments and many other applications.

A prominent feature of prism is that it can simulate the reflection of light in prism medium as a plane mirror system. Replacing mirror assemblies can be useful prism applications because they both refract or fold light and change image alignment. To achieve the effect of a single prism, it is usually necessary to use multiple mirrors. Therefore, using one prism instead of several mirrors can reduce the potential calibration errors, improve the accuracy and reduce the scale and complexity of the system.
