Thanks Nick
I'll be measuring light through a monochromator...so at a time I'll have only one (or a set of very closely spaced) wavelengths)
By linearity,i imply that after calibration for a particular wavelength,the output should be proportional to the power of light falling on it for that wavelength.
also the measurements will be performed in a dark chamber so there will be no external interference.
Keeping this in mind,which type of sensor shall be best (and,hopefully,simple to implement) ?
thanks again
