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.

Specification:

Substrate material: KU-1, K8 Surface figure @ 633nm: l/10 Surface quality, scr/dig: 20/10 Clear aperture: exceeds central 85% of dimension Dimensional tolerance, mm: +0/– 0.2 Angular deviation, mm: ± 0.3 Coating: dielectric, metal-dielectric, metallic; user specified Damage threshold, J/cm2: 2-5, depending on coating spec.

Here is an example of the prism coating:
