"WebSounds like the setup has the correct order. I think what you need to consider is that the light spreads after the grating and the whole spectrum should fit the lens, otherwise you'll miss part of it. No interference should be present in the readings. Additionally, if the incoming light is not collimated, you might need a curved mirror or lens. " - Dvd diffraction grating
