Product Family Description

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

TECHSPEC® 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). 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.
