Constructed from reinforced fiberglass plastic (RFP) composite, RFP grating is used in hundreds of commercial, industrial and residential applications, including platforms, handrails, decks, foot bridges, catwalks, pond skimmers and more. Look for pultruded, moltruded and molded grating in the most popular sizes and configurations.
Plane ruled diffraction gratings are blazed for maximum efficiency in the first order Littrow configuration at specific wavelengths. Ruled reflection gratings are especially well suited for spectroscopic systems requiring high resolution. High efficiency at design wavelength and blaze angle
Diffraction Grating Handbook - Chapter 1 . THE GRATING EQUATION [top] When monochromatic light is incident on a grating surface, it is diffracted into discrete directions. We can picture each grating groove as being a very small, slit-shaped source of diffracted light. The light diffracted by each groove combines to form a diffracted wavefront.
Di↵raction Grating Equation with Example Problems1 1 Grating Equation In Figure 1, parallel rays of monochromatic radiation, from a single beam in the form of rays 1 and 2, are incident on a (blazed) di↵raction grating at an angle i relative to the grating normal. These rays are then di↵racted at an angle r.

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.
A diffraction grating is used to spatially separate light of different wavelengths. A typical diffraction grating consists of an optical material substrate, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum.
Steel Bar Grating, also known as Welded Steel Bar Grate is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle Bar Grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements.
Richardson Gratings is a world leader in the design and manufacture of diffraction gratings for spectroscopic, telecommunications and laser applications. Please see our Diffraction Grating Guide for more information.
Common Applications. Heavy duty expanded metal grating is produced from aluminum, stainless or carbon steel sheet and plate which contains no joints or welds, as each sheet is a single piece of sturdy steel. Light weight and economical, expanded metal grating is ideal for use wherever a strong, durable lightweight surface is needed.
Thorlabs offers ruled diffraction gratings for use in the UV region around 300 nm. These gratings will have a relatively sharp efficiency peak about the 300 nm blaze wavelength and are produced from ruled originals. They are offered with different blaze angles to suit a variety of app
TiteWeld™ Steel Bar Grating is ideal for very tight spacing requirements and maximum “roll-a-bility” requirements. TiteWeld™ bar grating satisfies ADA comfort requirements for wheel chairs and walking pedestrians. TiteWeld™ steel bar grating is Direct Metals' answer to applications requiring bearing bars placed close together.
Diffraction gratings and optical spectroscopy. A grating disperses light of different wavelengths to give, for any wavelength, a narrow fringe. This allows precise spectroscopy. Absorption and emission spectra. Gas and incandescent lamps. Physics with animations and video film clips. Light. Physclips provides multimedia education in introductory physics (mechanics) at different levels.

Diffraction Gratings: Theory and Applications 3 What is a diffraction grating? zIt is a device that reflects or refracts light by an amount varying according to the wavelength. zIt works in analogy to the prism. zBasically, a diffraction grating performs a Fourier Transform, separating a waveform in the time domain into a number of waveforms in the
