The purpose of an aspherical lens is to modify the curvature of the surface of the lens so that the focal points of the near and far axis rays coincide. When the paraxial light and the far-axial light fall on the same focal plane, the light spot will disappear and the image sharpness will be improved.

Our Technical process mainly includes:

• CNC machine
• moulding method
• SPDT (single point diamond turned)
