Calcium Fluoride Right Angle Prisms

Calcium fluoride right angle prisms are used to bend the optical path or deflect the image formed by the optical system by 90 °. It has a larger contact area and angles of 45 ° and 90 °, making it easier to install compared to ordinary mirrors, and has better stability and strength against mechanical stress. Applied to spectral optical windows, prisms, and lenses. UM OPTICS can provide calcium fluoride right angle prisms with a size of 2-100mm. It can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
