Aspherical optical components can effectively correct various aberrations in optical systems and improve imaging quality. They can replace multiple spherical components with one or several aspherical components, thereby simplifying the instrument structure, reducing costs, and effectively reducing the instrument weight. We adopt computer-controlled CNC polishing for aspherical lenses, which can achieve excellent surface flatness and focal length accuracy.
