Product Introduction
High-precision right angle prism can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source. These right angle prism are fabricated from N-BK7 N-SF11 7980 H-K9L JGS1, and they are offered in sizes Minimum 0.28 mm. Our N-BK7 right-angle prisms are available uncoated or with one of our three standard broadband antireflection coatings (-A: 400 - 700 nm, -B: 1250 - 1680 nm, -C: 1060 -D: 980nm) on either the hypotenuse or both legs, thereby reducing surface losses.
Due to total internal reflection (TIR), the right angle prism can be used as a 90° reflector. When the input light is incident on one of the prism's legs, it undergoes TIR at the glass/air boundary of the hypotenuse and exits via the other prism leg. This 90° deviation of the input light makes the right angle prism a suitable alternative to a mirror.
The right angle prism optical prism possesses the simple geometry of a 45-degree right triangle, and is one of the most commonly used prisms for redirecting light and rotating images.
