Silicon Right Angle Prisms

Silicon right angle prisms have high refractive index (about 1.59) and high transparency, with high-precision surface quality and optical performance. Silicon right angle prisms have high transmittance in the range of ultraviolet to near-infrared, and can resist the influence of environmental temperature and mechanical stress. They can be used for reflecting and turning light, changing the direction of the beam. It can also be used in optical systems as beam splitters, combiners, and imaging components to improve the performance and stability of optical systems. Micron optics can provide calcium fluoride right angle prisms with a size of 2-100mm.
