Abstract
We develop a new expression for the thermal contrast of a black-body radiator. The derivative of exitance of a blackbody radiator with respect to temperature, integrated over the wavelength interval, is given in a closed form. The thermal contrast is found within an interval using a series evaluation and a closed-form compensated approximation. The compensated approximation is more accurate than the series expansion for lower values of x, corresponding to high temperatures and/or longer wavelengths.
