Right Angle Prisms

Right Angle Prisms are typically used to bend image paths or for redirecting light at 90°. Right Angle Prisms are Prisms designed with a 90° angle. Right Angle Prisms produce inverted or reverted left handed images, depending on the orientation of the prism. Using two Right Angle Prisms together is ideal for image or beam displacement applications. These prisms are also known as image reflection or reflecting prisms.
