Right angle Prism
Right angle prism is the most widely used prisms. It utilizes the inherent total internal reflection (TIR) at the hypotenuse to invert the image and achieve a 90° change in direction.It is typically coated on the hypotenuse with Al /Ag/Au to enhance reflectivity.We have standard 3*3mm,5*5mm,10*10mm,20*20mm right angle in stock.
