Custom Optical Prisms
Optical prisms turn, invert, rotate, disperse or reshape an optical path. A useful prism drawing defines face angles, datum surfaces, roof or edge geometry, clear apertures, coatings and the relationship between optical and mechanical datums.
Materials & wavelength
Substrate routes
Optical glass, fused silica, CaF₂ and other UV-to-IR materials selected for dispersion, transmission and environment.
UV through infrared, with material and coating selected for the operating band.
End use
Typical applications
- Beam turning and optical-path folding
- Image rotation and inversion
- Spectral dispersion and wavelength selection
- Laser beam expansion and anamorphic correction

Reference manufacturing and RFQ targets
These values show the type of requirement that can be evaluated. They are not a blanket capability guarantee. The signed quotation, approved drawing, sample and inspection plan control the final product.
| Parameter | Reference target / quotation note |
|---|---|
| Size route | Reference RFQ range: approximately 0.5–100 mm, with custom geometry reviewed by drawing. |
| Clear aperture | Central 90% is a common target; usable face area should be marked on the drawing. |
| Face flatness | Targets to λ/10 at 632.8 nm can be evaluated. |
| Surface quality | 10-5 scratch-dig target can be evaluated for low-scatter applications. |
| Angular tolerance | Targets below 15 arcsec may be evaluated according to prism type and datum scheme. |
| Coating | AR, reflective, beamsplitter or total-internal-reflection face definitions by surface. |

What to include in your RFQ
- Prism type or complete dimensioned drawing
- Material, wavelength and dispersion requirement
- Face-to-face angular tolerances and datums
- Flatness, surface quality and clear apertures
- Coating assignment for every functional face
Final acceptance: Confirm all numerical values, material grade, coating curve, metrology, sampling plan and documentation on the purchase specification.

Buyer questions
Optical Prisms FAQ
Which prism dimensions are most important on an RFQ?
Identify optical faces, face angles, datums, clear apertures, edge or roof tolerances, material and coating. A marked drawing is safer than a prism name alone.
Can a prism work by total internal reflection?
Yes, when material index, wavelength and incidence geometry support it. External reflective coatings may still be selected for environmental or angular reasons.
Can prism assemblies be supplied?
Bonded, contacted or mechanically mounted prism assemblies can be reviewed when the alignment, adhesive, environment and acceptance test are defined.
