Abstract. Various approximations for irradiance distribution across diffusion disk of non-aberrational lens are considered. Contrast in the image of two point sources at minimal resolved separation is calculated and accuracy of results for each of the approximations under examination is analyzed.
Keywords: lens, diffusion disk, radiance, contrast.
