Diffraction Gratings minimize stray light.
Press Release Summary:
Blazed Holographic Diffraction Gratings are aluminum coated with ion-beam etching to create standard sawtooth design. Since technique eliminates need for diamond-tipped tooling, periodic structure errors that cause stray light are no longer present. Gratings are suitable for all varieties of spectrometers, spectrophotometers, and monochromators.
Original Press Release:
Edmund Optics Announces Blazed Holographic Diffraction Gratings
July 13, 2005, Barrington, NJ. Edmund Optics offers new blazed holographic gratings that 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. 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.
