| Zusammenfassung | A dedicated calibration technique was applied for the calibration of the spectral radiance transfer standard (RASTA) of the German Aerospace Center at PTB, consisting of two independent but complementing calibration procedures to provide redundancy and smallest possible calibration uncertainties. Procedure I included two calibration steps: In a first step the optical radiation source of RASTA an FEL lamp was calibrated in terms of its spectral irradiance E (λ) in the wavelength range from 350 nm to 2400 nm using the PTB Spectral Irradiance Calibration Equipment (SPICE), while in a second step the spectral radiance factor of the RASTA reflection standard was calibrated in a 0°:45° viewing geometry in the wavelength range 350 nm to 1700 nm at the robot-based gonioreflectometer facility of PTB. The achieved relative standard uncertainties (k = 1) range from 1.1 % to 6.2 % and 0.1 % to 0.6 % respectively. Procedure II was completely independent from procedure I and allowed to cover the entire spectral range of the RASTA up to 2500 nm. In the second procedure the 0°:45°-viewing geometry spectral radiance L of the RASTA was directly calibrated at the Spectral Radiance Comparator Facility (SRCF) of PTB. The relative uncertainties for this calibration procedure range from 0 8 % in the visible up to 7 5 % at 2500 nm (k = 1). In the overlapping spectral range of both calibration procedures the calculated spectral radiance L from procedure I is in good agreement with the direct measurement of procedure II. i.e. well within the combined uncertainties of both procedures. |
