Detectors based on CMOS matrices (CMOS is a complementary metal–oxide–semiconductor structure) are widely used to solve a wide range of problems that require imaging. In addition to their widespread use in conventional cameras, including mobile phones, today they are increasingly used in various fields of science and technology: dosimetry, imaging neutron and X-ray spectroscopy. On the basis of such devices, both X-ray microscopy devices and X-ray telescopes can be built, for example, for studying various astrophysical objects. The possibility of using two CMOS matrices from Sony IMX265LLR-C and IMX226CLJ-C for simultaneous imaging and spectral acquisition in the soft X-ray range is considered. It is shown that in the range from 1 to 22 keV, the detectors have a high energy resolution. A comparison of two matrices is carried out, and their features for use in recording radiation in various energy ranges are considered.
