Aspheric lens advantages disadvantages-VS spherical lens

Generally speaking, the spherical lens is thicker; the imaging through the spherical lens will deform. The aspheric lens, on the other hand, is thinner and lighter, and make a more natural and realistic image.

Besides, the aspheric lens has two main advantages:

aspheric vs spheric

On the other hand, what is the disadvantage of aspheric lens?

In the past, because the surface of the aspherical lens is more complex, grinding technology is used in the production, which is more difficult, but also needs more time and higher cost. Then glass molding occurs, which required very high temperatures to soften the glass, and the problem with high temperatures was that the tools would break easily, under this lousy condition, For that, the K-PG325 super-hadronic glass molding material dissolved at low heat at 325 °C was developed.

Aspherical lens manufacturing has four types, precision glass molding, precision polishing, diamond turning, and molded polymer aspheres. Aspherical lenses usually are more complicated, time-consuming, and expensive to produce. Molded polymer aspheres is an exception, but plastic lenses can not achieve the required precision, stability and compression are poor. Meanwhile, sorts of optic plastic are few.

In general, the aspheric lens is the trend of lens Development in the future. With optical development, aspherical lens market demand will be growing. Contact our support team no matter what level of aspherical lens you require. We will provide you with the best commercial-grade, precision grade, high precision grade of aspherical lenses.
