Problems solved by technology

Since the grating is rotated by a mechanical device in such a spectral analysis instrument, a certain scanning time is required to ensure the wavelength resolution, and the measurement speed is slow, and the optical index measurement of the measured optical materials and components cannot be obtained immediately, and the detection efficiency for large quantities of products is low.
Due to the use of precision mechanical rotating devices, the exi
