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.

The equations above may lead to values of sin θ out with a modulus larger than 1; in that case, the corresponding diffraction order is not possible. Figure 2 shows an example, where the diffraction orders −1 to +3 are possible. Figure 3: Output angles of a reflective diffraction grating with 800 lines per millimeter as functions of the

However, a diffraction grating has many slits, rather than two, and the slits are very closely spaced •. By using closely spaced slits, the light Is diffracted to large angles, and measurements can be made more accurately. In spreading out the available liKht to large angles, however, brightness is lost.

Anchoring Devices attach the bar grating to its supports. Direct Metals offers saddle clips, anchor blocks, plank clips, countersunk lands, grating clamps, Z clips, and plank lugs for bar grating projects. Many of these bar grating anchoring devices are available in aluminum, stainless steel, and galvanized steel.

Diffraction grating - Wikipedia

Diffraction grating - Wikipedia

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
