Right-angle prism mirrors are extremely versatile optical components, commonly used as individual prisms and components of optical assemblies. A beam of light entering the leg of a right-angle prism mirror will deviate by a nominal value of 90°, while precise rotation of the prism controls beam alignment. When light enters the hypotenuse of the prism, it is commonly called a Porro prism. In this configuration, a light beam will undergo 180° deviation that is invariant in the azimuthal axis,
Optical glass such as K9, fused silica, sapphire, MgF2, silicon (Si), ZnSe, ZnS, etc. These materials possess high transmittance, low absorption, low scattering, uniform refractive index, and specific dispersion characteristics.
Precisely hemispherical. The machining precision of the center and radius of curvature of the sphere is extremely high.
The surface is precision polished to an optical grade of 10-5 to ensure image quality and reduce scattering and aberrations.
An AR coating is typically applied to the concave surface to maximize the transmittance of specific wavelengths of light (e.g. visible light) and reduce reflection loss.
A right angle prism mirror is usually used to turn a light path or deflect an image produced by an optical system by 90°.Depending on the orientation of the prism, the image can be aligned left and right, upside down and left and right.Rectangular prism can also be used for image combination, beam deviation and other applications.
When a right angle optical prism mirror is used, some optical film is usually plated.The rectangular prism itself has a large contact area and such typical angles as 45° and 90°. Therefore, compared with ordinary reflectors, the rectangular prism is easier to install and has better stability and strength for mechanical stress.They are the best choice of optical parts for all kinds of devices and instruments.
