Abstract
A calibrated attenuator is demonstrated, operating on a well-known power distribution produced by diffraction. The diffracting object is a Ronchi ruling: Once its physical characteristics are known, the angular power spectrum provides a set of mutually calibrated sources over an extended intensity range. Precise measurements of the grating performance in the visible are referred, and scaling to NIR is demonstrated with generation of a number of calibrated sources. In pulsed laser operation the method is proved suitable to obtain a reliable ratioing to compute the peak value of the pulses, and to sample fixed attenuations.
