Schematic drawing

Rhomboid prisms are used to shift an incident beam without angular deviation or orientation change. In imaging applications, they will displace the optical centerline by the prism length “L” without inverting the image.

These prisms are available both uncoated and coated.


  • Lateral displacement of beam
  • Displaces optical axis without Inverting Image
  • Input and output beams parallel to ±30 arcseconds
  • Beam displacing Dove Prisms also available
