Rhomboid Prisms

Lateral Displacement of Beam
Displaces Optical Axis Without Inverting Image
Input and Output Beams Parallel to ±30 Arcseconds
Beam Displacing Dove Prisms Also Available

Rhomboid prisms are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prisms will displace the optical axis without inverting the image. The lateral displacement is equal to the length of the prism (specified by dimension D). Our TECHSPEC® Rhomboid Prisms feature high tolerance angles that keep the output beam parallel to the input beam to within 30 arcseconds. They are ideal for demanding displacement applications.
