System Advantages of Aspherical Lenses

Aspherical Lenses allow optical element designers to use less than traditional spherical element to calibrate the aberration, because the former aberration calibration provided for them than the latter using multiple surface aberration calibtion  offered. For example, the use of ten or more general zoom lens element, you can use one or two aspherical lens to replace five or six spherical lens, and can achieve the same or higher optical effect, reducing the production cost, also reducing the size of the system.

Use more  optical system of the optical element may have a negative impact on the optical and mechanical parameters, thus bringing more expensive mechanical tolerance, additional calibration procedures and more antireflection coating requirements. All of these results will ultimately reduce the overall usefulness of the system because users will have to constantly add support components to it. Therefore, adding aspherical lenses to the system (although the non-spherical lens price is more expensive than the f/# equivalent single lens and double lens ), it will actually reduce your overall system design cost.

Dissecting aspheric lenticular lenses

The term "aspherical lens" comprises anything that does not belong to the spherical objects. However, when we use the term here which is discussing  a subset of the aspherical lens in concrete, i.e. a rotating symmetrical optical element with a radius of curvature and a radial change in its radius will be presented in the center of the lens. The aspherical lens can improve image quality, reducing the number of components needed and  the cost of optical design. From a digital camera and a CD player to high-end microscope and fluorescence microscope, aspherical lenses are either in the optical, imaging or photonics industry, which are on the one hand, its application development is very rapid. For this, compared with the traditional spherical optical element aspherical lens have many unique and significant advantages.
