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

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.

Cinema lenses designed to create content tailored for online streaming utilize aspheres to shoot with a shallow depth of field while maintaining quality.

When doing basic imaging, how do you determine the magnification an optical lens will provide?

Collimated light occurs when light rays travel parallel to each other.

Although a common misconception, individual optical lenses do not always form an image when the object plane is placed a focal length away from the lens.

An understanding of refraction and basic ray optics is a critical foundation for understanding more complicated optical concepts and technologies.
