¿Qué es la lente asférica??

Una lente asférica es una lente cuyos perfiles superficiales no son porciones de una esfera o cilindro.. en fotografía, un conjunto de lentes que incluye un elemento asférico a menudo se denomina lente asférica.
The asphere’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations.
At present, our company has mastered the technology of producing aspheric lenses and has already applied that into the production of optical lenses. If interested, welcome for inquiry!
