Blazed Vs Sinusoidal Gratings

A diffraction grating can have a sinusoidal or blazed profile. A sinusoidal grating (generally just refered to as a hologrpahic grating) generally offers lower efficiency than a blazed grating, but often gives a broader spectral coverage. A blazed grating has a ‘saw tooth’ profile and normally offers higher efficiency.
