Anamorphic Prism Pair
Anamorphic Prism Pairs are precision optical components designed to expand or compress laser beams in one axis while maintaining beam quality for laser shaping, beam correction and optical alignment applications. Manufactured from fused silica, BK7 optical glass, N-BK7 and custom optical substrates as a matched pair of precision prisms with carefully controlled wedge angles, these components provide accurate beam magnification or reduction in a single direction without affecting the orthogonal beam dimension. Chenyu Optics manufactures anamorphic prism pairs uncoated or with AR, broadband AR and laser AR coatings for laser shaping, beam expander and alignment systems.
Anamorphic Prism Pair Overview
Anamorphic Prism Pairs are precision optical components designed to expand or compress laser beams in one axis while maintaining beam quality for laser shaping, beam correction and optical alignment applications.
By using a matched pair of precision prisms with carefully controlled wedge angles and optical surfaces, anamorphic prism pairs provide accurate beam magnification or reduction in a single direction without affecting the orthogonal beam dimension. They are widely used in laser systems, beam expanders, laser projection systems, optical communication equipment and scientific instruments where precise beam shaping is required.
Chenyu Optics supports custom anamorphic prism pair manufacturing according to customer drawings, including custom magnification ratio, prism angle, material and coating design for prototype and repeat production.

Beam Shaping Optics Comparison
| Anamorphic Prism Pair | Cylindrical Lens Pair | Galilean Beam Expander | Wedge Prism | |
|---|---|---|---|---|
| Beam Shaping Axis | Single axis, magnifies or reduces beam width in one direction only | Single axis, similar function using cylindrical curvature instead of prism wedges | Both axes equally, circular beam expansion | No magnification, beam deviates at a fixed small angle |
| Magnification Control | Set by prism wedge angle, continuously adjustable by rotation | Set by lens focal length ratio, fixed once assembled | Set by lens focal length ratio, fixed once assembled | Not applicable, fixed beam deviation only |
| Beam Quality Impact | Low distortion, preserves beam quality in the unaffected axis | Low distortion, but sensitive to lens alignment | Low distortion for symmetric beams | Minimal impact, mainly used for steering rather than shaping |
| Typical Use | Correcting elliptical laser diode beams, beam shaping systems | Line generation, one-axis beam shaping | Symmetric laser beam expansion for collimated systems | Beam steering, alignment systems |
