Aspherical Lenses
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. Please refer to the Coatings Section
Molded aspheric lenses are also available

 

Aspherical lenses are effective in the elimination of not only spherical aberration, but also other forms of aberration generated by lenses. Standa provides computer calculations and designing of aspherical lenses without spherical aberrations as well as low cost production of aspherical lenses made of Fused Silica, BK7 glass or other material upon your request. Our long time experience in production of aspherical elements lead to the development of low-cost, high image quality and high performance products. Aspherical lens is produced by exactly cutting away some part 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 it is from the optical axis of the lens. The spherical aberration causes a loss of image sharpness. Properly designed aspherical lenses fully compensate spherical aberrations. Aspherical lenses are effective in the elimination of not only spherical aberration, but also other forms of aberration generated by lenses. Aspherical lenses are also used to compensate for distortion aberration.
