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

Quickly Autofocus and Overcome Depth of Field Limitations

Optical lenses require very precise tolerances. Learn more about tolerances for spherical lenses at Edmund Optics.

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

Not all ruggedized imaging lenses feature the same type of ruggedization. Learn about the advantages and disadvantages of each type at Edmund Optics.

Aspherized Achromatic Lenses, exclusive to Edmund Optics, are doublet lenses consisting of two cemented optical elements that are matched for their color-correction ability and small RMS spot size.

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

Edmund Optics® manufactures several different types of ruggedized imaging lens assemblies.

TECHSPEC® Liquid Lens M12 Imaging Lenses from Edmund Optics combine a high-resolution with the electronic auto-focus of an integrated liquid lens

Single-Material Aspheric Achromats correct chromatic aberrations with a unique geometry, leading to numerous benefits over conventional achromatic lenses.

Have an application in a demanding environment? Learn about the different types of ruggedization: industrial, ingress protection, and stability at Edmund Optics.

Polarization Directed Flat Lenses, which are formed with polymerized liquid crystal thin-film, create a focal length that is dependent on polarization state.

Fresnel lenses are composed of a series of concentric grooves etched into one side of a sheet of plastic. Fresnel lenses are unlike typical spherical or aspherical optical lenses.

Fixed focal length, zoom, and macro lenses are all variable magnification lenses. Learn more at Edmund Optics.
