The spectral responsivity was one of the important parameters of deteetos. With the development of imag-ing technology, accurate measurement for the responsivity of scientific grade CCD cameras became more and more important. The technique about measuring the responsivity of CCD cameras was introduced. The calculation formula of the responsivity was deduced. Based on a responsivity facility in the institute, the responsivity of CCD cameras was measured by the system with the intensity of illumination. At the same time, part of tested results were given, and variety rule of responsivity change was obtained. Measurement results indicated that the responsivity tended to a constant with the increase of the illumination of CCD cameras, which according with the performance of real cam-eras.
