Aspherical Lenses
Features：
Simplified structure, reduced weight and size, surface profile
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.
