A question of intensity...
Hello to all the gentlefolk on PL,
I have what may seem like a silly question, Is it possible to convert the perceived intensity of a relatively monochromatic light source 'lumens' (i'm assuming photopic vision) in to a radiometric intensity milliwatts? Assuming that you know the wavelength and the average eyes response curve.
If so could somebody provide me with a formula to do this as even after an extensive searching, Google/my brain appears to have failed me!!!
Any help would be greatly appreciated
Matt
