I have a medical application where i need to measure the irradiance of a source light with a wave length of 470nm,and I have some ambient noise (sun and fluorescent lights)
I have already filter the ambient noise and I have a good reading of the irradiance all I need to know is the responsivity at 470nm exactly,
I also need to know how this responsivity changes from one device to another (repeatability).
thanks in advance for all the help that you could give me.
