Product Description Product DetailsTypical groove density range of the plane ruled gratings is from 20 lines/mm to 1800 lines/mm. Standard coating is aluminum. On request, MgF2,Gold or platinum are also available.Ruled diffraction gratingsRuled diffraction gratings are produced by ruling a series of closely spaced, straight parallel grooves into an optically flat aluminum coated substrate, known as the "master grating." Precise, interferometrically-controlled ruling engines utilize a very fine diamond tool to form a sawtooth-shaped groove profile at a given angle (commonly referred to as the blaze angle) on the surface of a prepared substrate. The replication process begins with the surface contour of a ruled master grating being vacuum deposition-coated with an extremely thin separation layer. An aluminum coating is then deposited on top of this separation layer. Then, an epoxy-coated flat glass substrate is placed on top of the layer-covered master, duplicating the grooved surface. The combination is cured and the process is finished when the replicated grating is separated from themaster grating..Grooves20~1800Lines/mmBlaze Wavelength250-10000nmBlaze Angle4.3°-52.7°Spectrum Length Coating19-26mmCoatingAluminunTypeReflective diffraction gratingsConstructionRuled gratingsShenyang Ebetter Optics Co., Ltd. has been engaged in more than 20 years.
