- Abstract
A plant and method of measurement of the spectral reflectance of samples of absorbing coatings of solar energy collectors situated at the center of an integrating sphere in the range of wavelengths 350-1100 nm and at angles of incidence 0-90° are described. Features of the process of measuring the diffuse optical density in reflected light are investigated. Results of measurements of the spectral reflectance of the samples in the above range of wavelengths are presented and a calculation of the integral reflectance at angles of incidence of the radiation 5-85° is also carried out.
