Plane Ruled Reflection Grating, 12.5mm, 500 nm, 26.7°, 1800 Gr/mm

The 05RG1800-500-1 is a plane ruled reflection grating, with dimensions of 12.5 x 12.5 x 6 mm, 1800 grooves per mm, 26.7° nominal Blaze angle, first order Littrow nominal wavelength of 500 nm, and coated with an aluminum coating.


Designed for first order Littrow use, Richardson Gratings' plane ruled reflection gratings are blazed for specific wavelengths and generally have high efficiency at those wavelengths. Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.
