2. THE PHYSICS OF DIFFRACTION GRATINGS

Diffraction by a grating can be visualized from the geometry in Figure 2-1, which shows a light ray of wavelength λ incident at an angle α and diffracted by a grating (of groove spacing d, also called the pitch) along angles βm. These angles are measured from the grating normal, which is the dashed

Grating efficiency | Revolvy

Grating efficiency Diffraction efficiency is the performance of diffractive optical elements \u2013 especially diffraction gratings \u2013 in terms of power throughput. It's a measure of how much optical power is diffracted into a designated direction compared to the power incident onto the diffractive element. If the diffracted power is designated with P {\displaystyle P} and the incident
