Rhomboid Prisms

Rhomboid Prisms
Rhomboid prisms (off-set prism) 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.


Applications:
• Imaging Optical System
• Optical Measurement System
• Optical Switches
• Beam Alignment
Other material ,sizes, tolerance and coatings are also available upon request.
