Calibration standard BN-LHSF-2P-20

Calibration standards Calibration standards enable the calibration and adjustment of measurement instruments to absolute measurement quantities. Calibration standards provide a reference signal corresponding to the measurement quantity to be calibrated. The reference signal of the calibration standard is calibrated in the respective measurement quantity. The calibration of the measurement instrument is performed by comparing the measurement signal of the measurement device with the standard specifications in the calibration certificate. Deviations are compensated for by adjusting the measurement instrument accordingly. Measurement of the spectral radiant flux The spectral radiant flux [W/nm] is important for qualification of illuminants based on their total emitted radiant power. The spectral radiant flux and its photometric equivalent luminous flux is therefore also used in the investigation of the energy efficiency of lamps. In order to measure the spectral radiant flux, the total light emitted by the lamp must be measured regardless of the radiation direction. Integrating sphere spectrometers and goniometers are typical measurement instruments for the spectral radiant flux.
