Uniformity measurements

Two different uniformity test equipments are used, one that uses a Xenon lamp and a set of interferential filters to select the wavelength (see Figure 6) and the other that use he QE measurements facility to obtain a monochromatic beam (see figure 7). An integrating sphere is used to obtain an uniform illumination over a large area in both equipments.
