Core of Aspherical Lens
The surface roughness of the aspherical optical mold core and the microstructure traces, such as turning tool marks, will be 100% transcribed on the surface of the injected plastic lens, resulting in abnormal results such as scattering and diffraction that affect the optical image quality. Therefore, a good surface roughness quality of the mold core is one of the key factors for stability of mass production of high-end lenses, especially for mega pixel product lens.
Senyun use the most advanced aspherical ultra precision processing equipments, which can meet the perfect quality requirements of no turning tool marks, and provide the best service in the high-end optical lens industry.
