The absolute electrical substitution radiometer is the way to ensure highly accurate and stable measurement of optical power in wide range of optical wavelength. Its sensitivity is mainly determined by temperature stability of the equithermal bath and electrical noise of temperature readout. In this article we investigate the noise background of different preamplifiers in combination with different types of temperature sensors for this purpose. The 1/f noise of temperature sensors and Johnson thermal noise were chosen as a figure of merit for sensors and preamplifiers, respectively. The results from our measurements are discussed.
