Prisms
Prism Type |

Material |
Application |
Right Angle Prism |
|
BK7 UVFS |
90° or 180° light reflection. 3 faces are polished |
Dispersing Prism |
|
BK7 SF11 |
Dispersing prism has three equal 60° angles. It is ideal for wavelength separating applications. 2 faces are polished. |
Dove Prism |
|
BK7 |
1)Light propagated along the longitudinal axis is inverted by 180°. 2)Light incident on the longest face of the prism is retroreflected and inverted by 180°. |
Corner Cube Retroreflector |
180° light reflection |
BK7 |
Corner Cube Retroreflectors are designed to reflect the beam entering the prism face, regardless of the orientation of the prism, back onto itself. As a result, corner cube retroreflectors are ideal where precision alignment is difficult or time-consuming. |
Penta Prism |
|
BK7 |
A Penta Prism deviates an input beam or image through 90° without inverting or reversing the image. In addition, the 90° beam deviation is not dependent on a precise alignment of the prism with respect to the incoming beam or image. |
Wedge Prism |
|
BK7 UVFS |
Wedge Prism is ideal for laser beam steering applications. It deflects a beam normal to the prism's perpendicular surface through an angular deviation. Wedge prism can be used individually or in combination with another wedge prism for beam steering. |
