ROD Lens
Rod Lenses (Cylindrical Glass Rods)
Rod lenses are precision-ground cylindrical optical components with polished outer circumferences and flat end faces, designed primarily for line beam generation and anamorphic laser beam shaping.
Functions:
Transforms a circular laser input beam into a uniform straight line beam along its transverse axis through side-surface cylindrical refraction, allowing flexible beam divergence control in precise optical alignment tasks.
Applications:
Barcode scanners
Self-leveling laser levels
Optical alignment systems.
Laser distance meters (LDMs)
Precision laser line generators
Machine vision line-light illumination

1. Standard products: The section is not polished and the cylinder is polished.
2. Customized section polishing, but with a minimum order quantity limit.
3. Other diameters and lengths can be ordered.
Information and Notes
1. Rod lenses function by refracting light through their side circumference to convert circular laser beams into uniform line beams; light is emitted transversely from the side wall rather than focused linearly from the end faces.
2. Manufactured from high-purity optical glass with precision outer-diameter tolerances and fine surface polishing to ensure minimal beam distortion and high line uniformity.
3. Custom specifications—including non-standard diameters, customized length trimming, optically polished flat end faces, chamfering, and Anti-Reflective (AR) coatings—are available upon request.
4. Spectral transmittance curves represent measurements at normal incidence (0° angle of incidence). Non-transmitted light within the spectrum is absorbed by the physical optical properties of the glass substrate.
5. Website specifications are provided for reference only. Final production and delivery comply with mutually agreed engineering specifications and actual physical products.
