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. |

Properties and Application |
|
BK7 |
 |
Penta prism deviates an incident beam without inverting or reversing to 90° . It is used commonly in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. |
|
BK7 |
 |
By adding a wedge and with partial refractive coating on surfaces S1, it is used as a beamsplitter, in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. |
|
BK7
UVFS |
 |
It is composed by two 30° dispersion prisms and a right angle prism. When a beam incident in one of the two surfaces (S1 & S2) at Brewster angle, then the beam will output at Brewster angle too from another surface, and beam is deviated 90 degree. It is often used as a dispersion prism. |
|
BK7
UVFS |
 |
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. |

UVFS
SF-14 |
 |
A commonly used optical component for dispersing the spectrum. |
|
BK7 |
 |
Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation the incident beam. |
Roof Prisms |
BK7 |
 |
Roof prism can invert and reverse an image, also, deflect the image 90° . Therefore, it is often used in terrestrial telescopes, viewing systems and rangefinders. |
Dove Prisms |
BK7 |
 |
Dove prism has two applications. The main application is used as a rotator. And when the prism is rotated about the input parallel ray through some angle, the image rotates through twice that angle. Another application is used as a retroreflector. |
