Calibration standards for spectral radiance Spectroradiometers and other instruments suitable for measuring spectral radiance are typically constructed with lens based entrance optics. To calibrate and correct these measuring systems, a uniform light source of sufficient size is required as a reference, calibrated in spectral radiance. Calibration standards for spectral radiance and uniformity Multi-spectral and hyper-spectral spectral systems produce multi-spectral and hyper-spectral images. In addition to the calibration and the matching of these systems for spectral radiance, a uniformity adjustment of the pixel sensitivity is required. Calibration standards for spectral radiance and uniformity must be characterized by a highly uniform light output field. Light output port In order to reduce the influence of reflections and shadows at the edges of the illuminated field, the output port has to be implemented with a thin edge, so-called ‚knife edge‘. Additionally, it is recommended that the outer 10 % of the exit port’s diameter is not used.
