Right-angle optical prism

fused silicaBK7

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. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted. Right angle prisms can also be used in combination for image/beam displacement. It is typically coated on the hypotenuse with Al /Ag/Au to enhance reflectivity, while the input and output faces are coated with MgF2 (a common AR coat).3mm/5mm/10mm/12.7mm/20mm/25.4mm/30mm could be quick supply from Yutai Optics. Product Description Yutai's suggestion for your choice: a.Right-Angle Prism with AR Coating on the hypotenuse if you wish to use your prism as a retroreflector and you want to reduce surface reflections over the specified wavelength range of the coating. b.Right-Angle Prism with appropriate AR Coating on the legs if you wish to use your prism as a 90 degree reflector and you want to reduce surface reflections over the specified wavelength range of the coating.
