Diffraction Gratings are optical components used to separate light into its component wavelengths. Diffraction Gratings are used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating’s surface.;The greater the groove density, the better the optical resolution possible, but the more truncated the spectral range. Spectral Range: The dispersion of the grating across the linear array; also expressed as the “size” of the spectra on the array. The spectral range (bandwidth) is a function of the groove density and does not change.;We describe recent research into devices based on fibre Bragg gratings in polymer optical fibre. Firstly, we report on the inscription of gratings in a variety of microstructured polymer optical fibre: single mode, few moded and multimoded, as well as fibre doped with trans-4-stilbenmethanol.;Using a sensor fabricated from a Poly Siloxane polymer (Methyl Vinyl Silicone rubber) spherical cap 50 mm in diameter, 6 mm deep with an embedded 10 mm long Bragg grating we have characterised the first and second moment of the grating spectral response when scanned across triangular and semicircular periodic structures both with a modulation ;Download Grating Calculator for free. Grating Calculator is a freeware application for the Calculation of Focal Planes of General Diffraction Gratings, from Rowland Type to the most modern aperiodic line density concave gratings used for soft x-ray diffraction.;Buyer's guide > Products > diffraction gratings. Where to Buy Diffraction Gratings. Diffraction gratings are optical devices containing a periodic phase or amplitude structure. They may be used for grading spectrometers and monochromators or for the stretching and compression of ultrashort pulses.;United Kingdom Phone: +44 1245 491 499 Optical Gratings. Optical gratings, also known as multiple slits, function due to a process called diffraction. Using a single beam holographic technique produces a grating with a sawtooth profile that is blazed at approx. 250 nm for each angle of incidence and each groove spacing. The result is a
