optical glass right angle prism

High-precision right angle prism manufactured from N-BK7, K9, or UV Fused Silica optical glass, featuring a 90° apex angle with two perpendicular faces and one hypotenuse face.

Designed for 90° beam deflection, image inversion/rotation, and total internal reflection applications.

Commonly used in binoculars, microscopes, periscopes, interferometers, and laser alignment systems. Available in custom sizes, angle tolerances, and AR/reflective coatings for OEM and scientific research projects.
