Required beam function
Start with path folding, image rotation, dispersion, fine steering or return-to-source alignment, then select prism geometry.
PRODUCT FAMILY
Right-Angle Prisms
Right-angle prisms turn an optical path by 90 or 180 degrees using reflection from the hypotenuse face.
Standard, high-precision and laser-grade families in K9 optical glass and UV fused silica cover general alignment through demanding wavefront applications.

6 product families are available. Use the engineering filters below to narrow the catalog before comparing exact models.
Angular performance
Compare apex or deviation angle, angular tolerance and transmitted or reflected wavefront at the system wavelength.
Aperture and coating
Confirm usable aperture, substrate and coated-face orientation before fixing the mechanical layout.

SELECTION QUESTIONS
Right-Angle Prisms FAQ
Technical answers to the questions that most often affect model selection.
How do I select the correct prism geometry?
Start with the required optical function: right-angle prisms fold a path, Dove and roof prisms control image orientation, dispersing prisms separate wavelengths, wedge prisms provide fine beam steering, and corner cubes return a beam toward its source.
What is the difference between K9 and fused-silica prisms?
K9 optical glass is cost-effective for visible applications. UV fused silica offers ultraviolet transmission, lower thermal expansion and better resistance to thermal shock. Material dispersion must also be considered for spectroscopy and broadband systems.
Which prism tolerances should be specified?
Review angular tolerance, dimensional tolerance, surface flatness, surface quality, transmitted or reflected wavefront and coating. For retroreflectors, also verify return-angle or beam-deviation performance at the model level.
Need a different diameter, tolerance or coating?
Send your material, wavelength, dimensions and quantity for review.
