The company has launched a laser wavelength detection system solution that integrates integrating spheres, fibers, and spectrometers. It has the characteristics of fast, convenient, low stray light, accurate, and scalable spectral bands for detecting spectra. Its cost-effectiveness is very high, which meets the needs of Chinese industrial and scientific research customers. Users only need to connect to a computer to detect characteristics such as wavelength and peak width within 10 milliseconds. The spectrometer in this system has high resolution and is suitable for continuous or pulsed laser emission spectroscopy testing with narrow half wave width. For high-power lasers, additional attenuation plates need to be added to attenuate excessively strong lasers.
