WebMar 31, 2024 · The efficiency to the specified diffraction order is assumed to be 100%, meaning all rays incident on the diffractive surface will exit at the diffraction angle of the specified order. The sign of the diffractive order determines the sign of the diffraction angle with respect to the optical axis. WebA blazed grating – also called echelette grating (from French échelle = ladder) – is a special type of diffraction grating. It is optimized to achieve maximum grating efficiency in a given diffraction order. For this purpose, maximum optical power is concentrated in the desired diffraction order while the residual power in the other orders ...
