We have a range of “reflecting prism solutions” the most common reflecting prism being the Right Angle Prism. Right Angle Prisms are normally used for image displacement, turning a beam by 90° or as external reflectors when the hypotenuse face is coated with a reflective coating.

Several grades and options are available.
Uncoated Right-angle Prisms allow for total internal reflection of up to 100% (not including absorption losses)
Right-angle prisms with aluminized hypotenuse face. For use as external reflectors.
Right angle prisms with protected faces the hypotenuse face is aluminized and black painted for protection, increasing the reflected incident angle.
Right angle prisms with AR coatings. The AR Coated type achieve 99% overall efficiency.

Several grades of quality are normally available, ¼ wave polished faces with angles better than 1 arc minute, or 1 wave polished faces with angles to 5 arc minutes.
Right angle prisms are generally available in BK7 or equivalent material for Visible/ NIR use or UV grade fused silica for UV use at 175nm.

Specification:
Dimensions: +0/-0.2mm
Angles: <3 or 5 arc minutes (Dependent on grade)
Flatness: <1 or ¼ wave (Dependent on grade)
Surface quality: 60-40 scratch/ dig
