Right Angle Prisms – 90°/180° Beam Folding & Image Inversion
Detailed Description:
Right Angle Prisms are the most common prism type, featuring a 90° angle and two 45° angles. They can fold a beam by 90° (using the hypotenuse as a reflective surface) or invert an image by 180° (using the two legs as reflective surfaces), making them ideal for beam steering, image rotation, and optical path folding.
