Precision Polished Aspheric Lenses
Chenyu Optics manufactures precision polished aspheric lenses according to customer drawings and optical specifications. Available options include custom materials, diameter, center thickness, focal length, aspheric profile, surface quality and wavelength-specific coatings for laser, imaging, machine vision and scientific instrument applications.
Precision Polished Aspheric Lens Overview
Precision polished aspheric lenses use a controlled non-spherical surface profile to reduce spherical aberration and improve focusing or imaging performance within a single optical element. Unlike molded aspheres, polished aspheric lenses are manufactured through precision generating, polishing and profile inspection processes, making them suitable for custom geometries, specialized materials and demanding optical specifications.
Material, diameter, center thickness, effective focal length, conic constant, aspheric coefficients, clear aperture, surface quality and coating requirements can be specified according to the customer drawing. Final manufacturability and tolerances are confirmed through engineering review.
For drawing-based designs, see Custom Aspheric Lenses. Compare production methods with Precision Molded Aspheric Lenses, or review our Optical Polishing, Optical Coating and Optical Metrology Inspection capabilities.

Aspheric vs. Spherical Lens Comparison
| Spherical Singlet | Spherical Achromatic Doublet | Aspheric Lens | |
|---|---|---|---|
| Aberration Correction | Uncorrected spherical aberration | Chromatic aberration corrected; spherical aberration remains | Spherical aberration corrected within a single element |
| Element Count | One element | Two cemented elements | One element |
| Typical Function | Basic focusing or imaging | Color-corrected focusing | High-quality focusing with reduced element count |
| Typical Applications | General-purpose beam shaping, focusing | Imaging systems requiring color correction | Laser systems, imaging, machine vision, scientific instruments |
Precision polished aspheric lenses are generally selected for custom geometries, specialized materials, prototypes and optical requirements that cannot be met by an existing molded design. Precision molded aspheric lenses are typically more suitable for repeat production when tooling cost and production quantity justify the molding process.
