Abstract

For imaging spectrometers in the range of 350 - 2500 nm spectral characterization is accomplished currently at the Calibration Home Base (CHB) facility at DLR Oberpfaffenhofen using a Quartz-Tungsten-Halogen (QTH) lamp and a monochromator illuminating one pixel at a time. Here a new concept of spectral measurements is presented by making use of a laser driven optical parametric oscillator (OPO) tunable through the spectral region of 405 nm to 2550 nm allowing to characterize all of the pixels simultaneously. The advantages as speed of measurement due to higher spectral radiance, easier alignment and better spectral distribution of illumination are discussed.
