Optical prisms are components with at least two polished plano surfaces separated by a wedge angle. These elements are used to reflect or refract light. Optical prisms can be found in dual channel instruments, anamorphic systems, imaging systems or any other application where beam steering and/or image manipulation is needed.
Optimax prism manufacturing capabilities available with one week delivery include:
Optimax prism-related capabilities are listed below. Due to having more than three sides polished or complex coatings, these components require longer deliveries:
Below are basic guidelines for defining part geometry:
Figure 1 shows the geometry of two sided wedges can be defined by an angle and a thickness.
Image above: Minimum Specifications for Wedges
The angle is the inclination of the two surfaces and the thickness a separation at some point. The separation only needs to be positionally defined at one location on the optic. Specifying the thickest edge provides the easiest access for measurement and is preferred by Optimax. Specification can be the thinnest edge or centerline thickness if desired.
The geometry of three sided prisms is defined by two angles and an altitude. The third angle and sides then become references. Outer shapes (perimeters) are typically rectangular, round or elliptical but can be anything within Optimax’s shaping capabilities.
