Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating's surface. Diffraction Gratings can be either transmissive or reflective. As light transmits through or reflects off a Grating, the grooves cause the light to diffract, dispersing the light into its component wavelengths.;C – Safe Concentrated Load in lbs. per foot of grating width. D – Deflection in inches. Loads and deflections given in this table are theoretical and are based on a maximum allowable fibre stress of 18,000 .
