I am working on a project that requires me to reverse engineer a BioPhotometer and build a new one with modifications. The part where I am stuck is a photodiode that measures wavelengths between 230nm to 600nm.
I know fundamentals of photodiodes, but I was not sure if a single photodiode can measure this range of wavelengths. ?
Or are there special photodiodes (array) that have multiple photodiodes built into them which measure different wavelengths and hence combine to make a broad spectrum photodiode equivalent. ?
Hope I have made this clear.
