Right
Angle and Knife Edge Prisms
We offer these prisms uncoated or with four different coating options,
namely:
- Broadband
Multilayer Anti-Reflection coating on legs
- Protected
Aluminum on hypotenuse and Broadband
Multilayer Anti-reflection on legs
- Protected
Aluminum on hypotenuse
- Protected
Aluminum on legs
- Broadband
Multilayer Anti-Reflection coating on hypotenuse
|
These are some of the most versatile prisms available. They can be
used as internal or external reflectors or as retro-reflectors according to
the orientation of the prism with respect to the incoming light. An uncoated
prism will act as a mirror for light incident on one of the short sides
(legs) since incident light Is totally internally reflected at the
hypotenuse. (TIR occurs when the angle of incidence is greater than the
critical angle which for the glass-air interface occurs at 41.2 degrees). Even
though uncoated prisms work well their useful full field of view is limited
to 10 or 12 degrees in the visible. It is recommended that appropriate
coatings be added to optimize the range of prism uses. |
|
The Broadband Multilayer Anti-Reflection coating will withstand high
power laser use, while the Protected Aluminum coating is evaporated aluminum
overcoated with a layer of MgF2 to protect it from scratches and
abrasions. See AR Coatings for the
Broadband AR transmission curve and HR Coatings for the
Protected Aluminum reflectivity curve.

While standard sizes are usually more cost effective when you need only
a few components we will be pleased to quote on special and volume
requirements. Just call for further information.
|
If you need one of our prisms as soon as possible - just ask for
next-day delivery. We try very hard to keep standard prisms set aside for
immediate shipment -- so you won't find yourself caught short trying to
finish a project. We also have a wide range of special prism sizes and shapes
available. |
