Precision Optical Aspheric Lens

Aspheric Lens the curvature radius of one surface varies with the height from the optical axis, effectively increasing the numerical aperture of the lens and reducing system aberrations. An aspheric lens spotlight can replace multiple spherical components, thereby reducing the cost of the entire optical system and improving transmittance.
