0.65μm radiation thermometers are used as the standard thermometers at high temperatures. The spectral stability of these thermometers influences largely on the calibration uncertainty. Therefore it is important to check the spectral stability. Usually spectral stability was estimated by using monochromators. But it is difficult for a calibration laboratory to maintain a monochromator to measure the spectral characteristics of the radiation thermometers. We propose to use two fixed-point calibrations to check the spectral stability. We compared the effective wavelengths obtained from the monochromator and those from the fixed point ratios. For the fixed points, copper and silver were employed. Unfortunately the silver point is almost the lower limit of the 0.65μm radiation thermometers. Resolution and uncertainty in determining the output ratio between copper and silver points were contributed mainly from the short-term and long-term stability of fixed points which were about 0.02% and 0.1% of the radiation thermometer output. These values correspond to 0.08nm resolution and 0.6nm uncertainty for the effective wavelength estimation.
