Ruled gratings Product
Diffraction ruled gratings are used in a variety of monochromators for research, student and industry use. Almost all commercially available spectrophotometers (ultraviolet, visible, infrared, fluorescence, Raman, atomic absorption) utilize diffraction gratings to select specific wavelengths or scan over a wavelength interval. As a general rule, replicated ruled gratings should be used when high peak efficiency and throughput is required. Replicated holographic gratings should be used when minimum stray light is critical and high resolution is needed. Note: Damage thresholds for both ruled and holographic gratings are 350 milli-joules/cm2 for pulsed lasers and 40 Watts/cm2 for CW lasers.
