Various types of steel gratings are placed on the ground.

The most common size of bar grating has bars that are spaced 1-3/ 16 inches (center to center) with perpendicular cross bars spaced 4 inches apart (center to center). In our industry, Bar Grating is most commonly used to create floors for mezzanines. Bar grating is used as an alternative to a plywood floor, supported by steel roof decking.Therefore, the 25,400 lines/inch grating should be used in applications that require the spectrum to be spread over a broader area and the 12,700 lines/inch should be used when more diffraction orders are needed to be viewed. Each variety of holographic grating is available in 6" x 12" sheets and 200 foot rolls.Thorlabs offers a selection of ruled diffraction gratings optimized for peak polarized efficiency in the mid-IR region. These gratings are offered with different blaze angles to suit a variety of applications. For information regarding the differences between grating types, please click on the GratiDiffraction 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.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.Those grooves or opaque lines diffract the incident light depending on its periocity and microstructure. Depending on the light's incidence angle, rainbow-colored patterns are discernible on a projection surface behind a transmission or reflection grating (except for gratings of the zero order). The colored patterns are known as optical spectrum.

Our pattern of leadership in optics has been hallmarked by the continuing development of both classically ruled and holographic diffraction grating technologies. This led to the introduction in 1967 of the aberration corrected holographic grating and subsequently ion etched and blazed concave and plane holographic gratings.observed diffraction lines are never infinitely narrow ( as expected from the theory ) , this phenomenon is a consequence of the not ideal experimental conditions and because of the Doppler effect. The equation of the grating shows that the diffraction angle depends only on the pitch of the grating and not by the shape of the slits.Aluminum Bar Grating, also known as Swagged Aluminum Bar Grate is light weight, yet strong and durable for all load bearing applications that need high corrosion Grating is available in a variety of bearing bar spacing, thicknesses and heights 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.

This grating gives multiple spectra at 45 degree intervals around the light source. The high line density produces a wide coloured spectrum of the observed or projected light source similar to that from a prism.High-efficiency gratings are desirable for several reasons. A grating with high efficiency is more useful than one with lower efficiency in measuring weak transition lines in optical spectra. A grating with high efficiency may allow the reflectivity and transmissivity specifications for the other components in the spectrometer to be relaxed.
