Laser Grade Right Angle Prisms

產品名稱 : Laser Grade Right Angle Prisms
產品說明 :
● Total internal reflection prisms
● 90° or 180° beam deflection

These uncoated right angle prisms may be used for beam deviation or as substrates for beamsplitters. When a beam enters normal to one of the legs of the prism it arrives at the hypotenuse face at an incidence greater than the critical angle. It is totally internally reflected at the hypotenuse and emerges normal to the other leg face. If the beam is input normal to the hypotenuse face it undergoes two total internal reflections at the leg faces and emerges in the opposite direction (180° deflection).
