Abstract

The fiber spectroradiometer is now widely used in the photometry and radiometry due to the convenience. Before use the calibration is usually traced back to the tungsten lamp with known spectral irradiance. However, the working condition may differ greatly from the calibration condition, such as the signal level, the spectrum shape, and et al. In the experiment, characteristics of the fiber spectroraidometer are investigated, such as the short time stability, the nonlinear phenomena due to the integration time and signal level. Uncertainty of the calibration is evaluated taking all the factors into account.
