Calibration standard BN-0001

irradiance

Calibration standards Calibration standards enable the calibration and correction 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 comparison the measurement instrument accordingly. Spectral irradiance The spectral irradiance [W/m²·nm-1] is important for qualification of the incident radiant flux of a reference plane. Spectralradiometers are the typical measurement devices for the spectral irradiance. Calibration of the spectralradiometer is done using a calibration standard lamp for the irradiance. BN-0001 calibration standard lamp Gigahertz-Optik GmbH offers the BN-0001 calibration standard lamp for applications where vertical alignment of the calibrating device is required. This has a 1000W DXW quartz halogen bulb for the usable spectral range between 250 and 2500nm. The lamp is firmly fixed into the socket. The electrical contact is installed through braze-welding. This sophisticated mounting and electrical connection ensures maximum position accuracy of the lamp and maintains a constant electrical resistance at the contacts. The standard lamp connection is done using robust ceramic terminal strips. Each standard lamp is burned-in before it is calibrated.
