In high-end optical manufacturing, precision processing and accurate testing of large-aperture optical components are essential to advancing aerospace, precision instruments, and optoelectronic systems. Led by a Ph.D. in optical manufacturing, the Advanced Optical Manufacturing Center of Wavelength Optoelectronics focuses on precision manufacturing of high-end optical components. With advanced processes, cutting-edge equipment, and rigorous inspection standards, it has built a comprehensive processing and testing system for large-aperture optical components, providing solid technical and process support for the manufacturing of Wavelength OE‘ large-aperture lenses.
