In the last decade the specific detectivity of InGaAs-photodiodes has improved significantly. Hence, the lower detection limit of InGaAs-photodiode based radiation thermometers at 1.6 μm can be extended. Here, an existing radiation thermometer was equipped with a state-of-the-art InGaAs-photodiode. The radiation thermometer was characterized and calibrated and a reference function has been compiled. The lower temperature limit could be extended from 150 °C down to 80 °C.
