Prisms


Prisms are blocks of optical material with flat polished sides arranged at precisely controlled angles to each other, which deflect, deviate and rotate beams of light as well as dispersing their wavelengths. Tempotec offers many types of high precision prisms as follow.

Penta Prism
Penta prism can deviate an incident beam without inverting or reversing to 90. The deviation angle of 90 is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Rangefinding ...
Beamsplitter Penta Prism
By adding a wedge and with partial reflective coating, Penta Prism can be used as Beamsplitter. It is often used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling. Transmission/reflection (T/R) ratio of 20/80, 50/50 or others for Beamsplitter Penta Prism is available upon req...
Right Angle Prism
Right angle prism is deviating or deflecting a beam of light with 90° or 180°. It is often used in telescope, periscope and other optical system. Furthermore, Laser grade right angle prism is also available by Tempotec. Please see the following chapter “ laser optics” for more informatio...
Dove Prism
Dove prism has two applications. The main application is used as a rotator. It can rotate an image but without deviating the beam. And when the prism is rotated about the input parallel ray through some angle, the image rotates through twice that angle. It is very important that the application must...
