High precision optical aspheric lens upon customers requests
Aspheric lenses are lenses made by heating optical glass until it can be placed into heat-resistant molds. Manufacturers then create individual variations of aspheric lenses. Aspheric lenses have been mostly used in eyeglasses, but in the past 30 years, they have been developed to be used for high-quality photography and as a standard for smaller photographic and video cameras.
Thanks to their smaller size, aspheric lenses have a thinner center, which makes them much lighter. Manufacturers can adjust the shape of the lenses while creating them, allowing for adjustments to each lens's focal power and clarity.

Advantages Over Spherical Lenses
Aspheric lenses are built to be cheaper and smaller than conventional lenses, and they often surpass the quality of lenses made from a spherical shape. Thanks to their manufacturing process, aspheric lenses are in continual improvement as technology moves forward.
