- 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
