Product Description

Why choose aspheric lens?

Aspherical lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.

Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept.
