Right Angle Prisms can bend light at either 90-Deg or 180-Deg and can be used for retro-reflectors, telescopes, and mirror substitutes etc. The right angle surfaces may come with anti reflection coating at different wavelength.
Materials: Commonly made from optical glasses like N-BK7, UV Fused Silica, N-SF11, Calcium Fluoride (CaF2), Germanium (Ge), or Zinc Selenide (ZnSe), chosen based on the desired wavelength range (UV, visible, IR) and performance requirements.
Applications: Beam steering and folding., Image reflection and inversion in optical instruments (e.g., binoculars, periscopes, telescopes), System alignment, Compact optical system design.
