neither a sphere or a circular, Used in applications to reduce beam
distortion, Other dimensions are available in small and mass
production quantities, Various AR Coatings are available for all
these lenses.
Applications：
Photographic camera lens, viewfinder, television camera tube, zoom
camera lens, satellite infrared telescope, video camera lens, Stage
light, Spotlight, bar code scanners, laser diode collimation, OEM
or R&D integration, Optical Measurement Systems, Projection
Optics Systems, Imaging Optics Systems, Astronomical Opticsetc,
etc.
Description:
A aspheric lens or asphere is a lens whose surfaces have a profile
that is neither a portion of a sphere nor of a circular cylinder,
but like paraboloid profile. Because asphperical lenses have
different radius of curvature from surface center to edge, so
aspherical lenses can eliminate spherical aberrations as well as
the error which other spherical lenses can not eliminate, promote
spotlight accuracy rate. At the same time, an aspherical lens has a
simple construction, an aspherical lens can replace multiple lenses
system, thereby reduce weight, size, and cost.
Aspherical lenses are effective in the elimination of not only
spherical aberration, but also other forms of aberration generated
by lenses. An aspherical lens is produced by exactly cutting away
some parts of a spherical surface. A standard spherical lens has
the undesirable property (called spherical aberration) of causing a
stronger diffraction of light rays the further they are from the
optical axis of the lens. Spherical aberration causes a loss of
image sharpness. Properly designed aspherical lenses fully
compensate spherical aberrations. Aspherical lenses are also used
to compensate for distortion aberration.
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.
