Penta Prisms
A penta prism features five surfaces (three polished, two reflective). The reflective surfaces are coated with metallic/dielectric HR coatings, and non-working surfaces are blackened. It deflects incident light by 90° non-reversibly, with the 90° deflection angle unaffected by minor positional adjustments for easy installation.
