Custom 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 custom right angle prisms to meet UV-Visible-NIR applications.

Custom precision grade N-BK7 or equivalent right-angle prisms: Custom precision grade right angle 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 available custom made to your complete bespoke specification with a range of accuracy to meet your application. Custom precision grade right angled prisms are available 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.

Custom standard grade N-BK7 or equivalent right-angle prisms: Our custom range of standard grade right angle prisms are similar to the precision grade versions but with lower surface quality and angular specifications.  Our range of custom range right angle prisms are more cost effective than the precision grade of RA prism and are available in a host of UV-Visible and NIR materials to create your cost effective custom right angle prism to meet all less demanding applications. Custom standard ranges of right-angle prisms are available 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.

Custom precision grade UV fused silica right-angle prisms: This custom made precision UV grade fused silica right angle prisms have high surface quality and tight tolerance angles. Custom precision grade UV fused silica prisms are ideal for applications as low as 175nm and achieve 85% efficiency at 185nm. Custom UV grade right angle prisms can also be coated 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.
