Aspheric Lens, Custom Design on Request
Aspheric curvature varies continuously from center to edge and with the central axis, improving optical quality and reducing lens count. Strong spherical-aberration correction supports instruments, focused imaging and optoelectronics. Imported grinding/polishing equipment uses computer-controlled milling and polishing with automatic surface-removal adjustment for precise automated production. Material, wavelength and coating can be custom designed.
