Blazed gratings ensure less stray light than conventional mechanically ruled gratings without any reduction in diffraction efficiency, by eliminating variability of the diamond-tipped tooling
Edmund Optics offers new blazed holographic gratings that it says ensure less stray light than conventional mechanically ruled gratings without any reduction in diffraction efficiency.
These gratings are ideal components in all varieties of spectrometers, spectrophotometers, and monochromators, it says.
Each grating is aluminum coated for maximum performance throughout the ultraviolet, visible, and infrared spectrums.
Ion-beam etching technology is employed to create the standard sawtooth design common to ruled gratings.
However, because the technique eliminates the need for diamond-tipped tooling, the periodic structure errors that cause stray light are no longer present, allowing these gratings to be used in instrumentation requiring excellent efficiency and resolution with minimal stray light and ghosting.
Edmund Optics has been a supplier of optics and optical components to industry since 1942, designing and manufacturing a wide array of multi-element lenses, lens coatings, imaging systems, and opto-mechanical equipment.
