What is an aspheric lens? In what applications are aspheric lenses used?

Edmund Optics® manufactures thousands of precision aspheric lenses per month in our asphere manufacturing cell that operates 24 hours a day.

No, advances in subaperture polishing have allowed for the fabrication of aspheres with surface figure error down to λ/20 (0.25µm). However, MRF is still...

The CNC polishing equipment used to fabricate the optics must have a large enough range of motion to properly polish the full asphere, and the weight of the...

CNC polished aspheric lenses offer high numerical apertures while creating diffraction-limited spot sizes and are ideal for high-precision applications.

Deviations in surface form relative to an ideal shape at higher spatial frequencies than Zernike polynomial aberrations but lower frequencies than roughness.

Lightweight, cost-effective aspheric lenses with a lower scratch resistance and thermal stability than molded glass aspheres.

Meta description: Ideal for volume applications, including laser diode collimation, bar code scanners, and optical data storage. Can be molded into diameters as small as 1mm.

Edmund Optics® (EO) manufactures millions of precision optical components and subassemblies every year in our 5 global manufacturing facilities.
