we
offers aspheric lenses to suit many applications. An aspheric lens
can be offered with a range of coatings for the Ultraviolet (UV)
spectrum, visible light, or Infrared (IR) spectrum. Aspheric lenses
utilize a single element design which helps minimize the number of
lenses found in multi-lens optical assemblies. The surface of
an aspheric lens is designed to eliminate spherical aberration,
providing diffraction-limited spot sizes. They are often employed
to collimate light exiting a fiber or laser diode.
