Semiconductor fabs and automotive LiDAR developers in North China often struggle with delayed calibration cycles for optical metrology equipment, leading to production line downtime and compliance risks. A newly inaugurated technical service center in Beijing directly addresses these pain points by providing local access to integrating sphere light source alignment, diffuse reflectance standard verification, and fluorescence quantum efficiency retesting. The facility reduces sample comparison and repair turnaround to within standard weekdays, compressing what previously took weeks. Equipped with on-site application engineers, the node supports critical tasks such as ADAS camera flat-field correction, LiDAR distance-reflectance joint calibration, and thin-film thickness inversion. By embedding regional technical response capabilities, the center enables faster iteration for wafer metrology and automotive perception systems without relying on overseas OEM lead times. This development reflects a broader shift toward localized, high-precision optical measurement services tailored to the demanding specifications of semiconductor and advanced mobility sectors.
