1.Feature of right angle prism:
Right angle prism also known as an image reflection prism that turn or deflect a beam through 90° or 180°. In either case this is achieved by total internal reflection and produces a very efficient broadband reflector. It is important that the incoming beam is collimated and enters the prism at a normal angle of incidence. This is so that total internal reflection can be achieved.
Substrate options include N-BK7, H-K9L, JGS1, Calcium Fluoride (CaF2), Germanium (Ge), or Zinc Selenide (ZnSe), Znc Sulfide (ZnS)
2.Application
To deviate the light path by 90° or 180°.
Used in Telescope, Periscope, Microscopy, Medical Instrument and other optical system.
Optics demonstrations in the classroom setting
Laser beam deflection
