600 Grooves, 1200nm Blazed Holographic Grating, 25mm Sq NT47-557
Less Stray Light than Ruled Diffraction Gratings Improved Diffraction Efficiency Over Holographic Gratings Broad Spectral Range Our blazed holographic gratings ensure less stray light than conventional mechanically ruled gratings without any reduction in diffraction efficiency. First, a holographic master grating is created by standard interference techniques. Then, a patented ion-beam etching technology is employed to create the standard sawtooth design common to ruled gratings. However, because the technique eliminates the need for mechanical ruling from 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. 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.
