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/cm²and 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^-4C/J/cm²at 575nm. Figure 4 shows the predicted responsivity of the photodiodes as a function of wavelength.
