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 a sphere intersected by a plane, aspheres or aspheric lenses are lenses with a non-spherical surface profile. For more information on aspheres, read All About Aspheric Lenses.
