Echelle replica gratings are special low period gratings designed for use in high orders only. The maximum possible resolution is obtained but, in general, it is necessary to use a second grating or prism to separate out the overlapping diffracted orders. Echelle replica gratings are an ideal solution for high-resolution spectroscopy due to their high dispersion in high orders.

If the displacement is parallel to the propagation direction (Figure 1(a)), the wave is a longitudinal wave. Sound waves are an example of longitudinal waves.

Any Optometrics grating is available with either standard or CW-type construction for higher  damage thresh­old performance. They can also be produced on substrates with a lower coefficient of thermal expansion for better stability. No damage threshold minimums apply to gratings with an overcoat.
