Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution. • High efficiency at specified wavelengths • Extensive selection of groove frequencies ranging from 50 to 2400 g/mm • Aluminum and gold coatings available • Float glass substrate • 12.5, 25, and 50 mm square sizes 100 90 80 70 60 50 40 30 20 10 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.2 1.4 1.6 1.8 2.0 2.2 2.4 2.6 Wavelength (ìm) ––– S - Plane - - - P - Plane Reflectance of Aluminum Efficiency (%) Plane Ruled Reflection Grating, 1200 g/mm, 17.5° nominal blaze angle, 500 nm blaze wavelength, aluminum coating Shown here is an example of an efficiency curve for our plane ruled reflection gratings. A complete set of curves are available on our website. Note: Many of these curves are relative (not absolute). They are only representative, and can vary significantly depending on use geometry and measurement technique. Two masters with the same catalog number may have different efficiency curves.
