Pentaprisms provide a fixed 90° beam deviation, ensuring stable output regardless of input beam angle.
They are widely used in DSLR cameras, laser scanning systems, and precision measurement devices.
Custom coatings such as AR, reflective, and beam-splitting layers are available for various wavelength ranges.
