10mm 13mm 18mm 20mm 30mm 50mm Plano Convex/concave Aspheric lens supplying
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations.
While in principle aspheric surfaces can take a wide variety of forms, aspheric lenses are often designed with surfaces of the form
Aspheric Lenses are used to eliminate spherical aberration in a range of applications, including bar code scanners, laser diode collimation, or OEM or R&D integration.
Our aspheric lenses are ground and polished on the plano side and precision molded on the aspheric side
