Attached is the normalized spectral response curve from the OPT101 photodiode datasheet. I attach the output from the photodiode to a 08M2 pin and issue a READADC command. Now suppose I shine a blue LED, with a wavelength of 500nm, on to the photodiode and the READADC reading is 21. With reference to the responsivity curve,is the value of 21 only 40% of the true value? Should the true value be 21/0.4 = 51?
