This paper presents an algorithm of numerical calculations of radiation heat transfer between optical surface elements. The algorithm is based on a generalised zonal method with spectral strip approximation and allows dependence of optical properties (reflectance, absorptance and emittance) on the temperature of the element, wave length, and direction of radiation to be taken into consideration.
