More Information About Aspheres

Aspheric Lenses are used to eliminate spherical aberration in a range of applications, including bar code scanners, laser diode collimation, or OEM or R&D integration. Aspheric lenses utilize a single element design which helps minimize the number of lenses found in multi-lens optical assemblies. Said another way, unlike conventional lenses with a spherical front surface, aspheric lenses have a more complex front surface that gradually changes in curvature from the center of the lens out of the edge of the lens. This reduction in total element count not only helps decrease system size or weight, but also simplifies the assembly process. Integrating aspheres into an application such as focusing the output of a laser diode may not only decrease total cost, but may also outperform assemblies designed with traditional spherical optical lenses.

FAQ(s)

  What are aspheric condenser lenses?
Aspheric condenser lenses are a specific type of optical lens called an asphere, ideal for condensing or focusing incident light rays for illumination and collimation applications. While spherical lenses are lenses that take the form of the shape of a sphere intersected by a plane, aspheres or aspheric lenses are lenses with a non-spherical surface profile.
