An optical spectrometer (spectrophotometer, spectrometer, or spectroscope) is an instrument used to measure the properties of light in specific parts of the electromagnetic spectrum, often used in spectral analysis to identify materials. [1] The variable measured is usually light, for example, but c

The automatic video measuring instrument is a modern optical non-contact measuring instrument, which is an artificial intelligence measuring instrument developed on the basis of digitization. This measuring instrument inherits the characteristics of digital motion precision and motion control, combined with the innovation of visual software.
