Prisms for YAG Lasers
Prisms are blocks of optical material with flat polished sides arranged at precisely controlled angles to each other. Prisms are used at an optical system to deflect or deviate a beam of light. They can invert or rotate an image, disperse light into its component wavelengths, and be used to separate state of polarization.
