enter image description hereI am designing a transmission grating based spectrometer. Can the angle of incidence on the grating (alpha) be unequal to the diffraction angle (beta)? I didn't think that they could be varied as i wished because they affect the focal lengths of lenses in the optical array. Thanks for your help
