3 / 9 page AMIS-734256, AMIS-734512, AMIS-734024 Data Sheet 25µm-pitch Wide Aperture Spectroscopic Photodiode Arrays During normal operation, the photons incident in or near the NP photodiode junction generate free charges, which are collected and stored on the junction's depletion capacitance. The number of collected charges is proportional to the light exposure. Figure 3 shows the stored signal charge as function of light exposure at a wavelength of 575nm. The exposure is the product of the light intensity in nW/cm2 and integration time in seconds. The charge accumulates linearly until reaching the saturation charge and the corresponding exposure is the saturation exposure. There are two saturation limits which are described in Section 4.0. The responsivity may be calculated as the saturation charge divided by the saturation exposure. The predicted typical responsivity of a photodiode is 1.5 ×10-4 C/J/cm2 at 575nm. Figure 4 shows the predicted responsivity of the photodiodes as a function of wavelength.
