Re: Difference between spectrocopy

... a particular wavelength (again, actually a narrow passband) and scanning through the spectrum of emitted light. This machine has two diffraction gratings, one controlling the wavelength of excitation light passing through the sample and the other controlling the wavelength of emitted light passing ...
