High-speed spectrometer based on a silicon CCD-array matrix for transient changes measuring in optical radiation spectra

The paper discusses the high-speed 400-1000nm range spectrometer based on the M150 monochromator and a silicon CCD-array matrix as a detector module. A description and general diagram of the complex is presented, consisting of the following main parts: optical part, communication, and digital and software sections. The current work considers specialized software for transmitting, processing, and outputting data management of the spectrometer through a graphical user interface which allows selecting the desired wavelength range, exposure time, and duration of the graph. The complex utilizes the FPGA hardware capabilities to process converted signals in situ, providing additional services to make optical spectra analysis easier for the operator. The main application field of the spectrometer is the research of rapid changes in the spectral characteristics of optical materials, such as optic fibers and laser-pump crystals, and products based on them when exposed to pulsed ionizing radiation. Other possible subjects of research and areas of improvement are highlighted.
