Ensure Less Stray LightBARRINGTON, N.J., Aug. 8 -- Edmund Optics is offering blazed holographic gratings that it says ensure less stray light than conventional mechanically ruled gratings without any reduction in diffraction efficiency. The gratings can be used with all varieties of spectrometers, spectrophotometers and monochromators.
The company said 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 that requires efficiency and resolution with minimal stray light and ghosting.
