Right angle prisms

What are you looking for in Stock?

Right angle prisms are simply triangular blocks of glass with two 45° and one 90° angles and are generally used to bend light, reflect light and for image displacement.

Knight Optical supply a range of stock right angle prisms to meet UV-Visible-NIR applications.

Precision grade N-BK7 or equivalent right-angle prisms: Precision grade prisms have high surface quality and tight tolerance angles. The normal use for a right-angle prism is to turn light through 90° by internal reflection from the hypotenuse. These right angle prisms are stocked with a variety of coatings to meet a variety of applications. Precision grade  prisms are stocked with the following options.

Uncoated range: All faces are left uncoated.
AR coated range: Antireflective coating on entry/exit faces to achieve 99% efficiency.
Protected range: Aluminised and black painted on Hypotenuse to achieve 90% internal reflection over a greater angular range.
External reflector range: Aluminised and protected on hypotenuse for use as mirrors.


Standard grade N-BK7 or equivalent right-angle prisms: Our stock range of standard grade of RAPs  are similar to the precision grade versions but with lower surface quality and angular specifications.  Our range of standard range right angle prisms are more cost effective than the precision grade of RA prism.  Various coatings can be applied to their faces. 


Precision grade UV fused silica right-angle prisms: These stock precision UV grade fused silica RAPs have high surface quality and tight tolerance angles. The normal use for a right-angle prism is to turn light through 90° by internal reflection from the hypotenuse. These right angle prisms are stocked as uncoated and protected on the hypotenuse to meet general applications. Precision grade UV fused silica prisms can also be coated with the following options:
AR coated range: Antireflective coating on entry/exit faces for UV use achieving over 85% efficiency.
External reflector range: Aluminised and protected on hypotenuse for use as mirrors.
