Ruled Reflective Diffraction Gratings

Ruled Reflective Diffraction Gratings

Diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized reflective film, which can separate white light into various components through diffraction effect. High-quality ruled diffraction gratings can meet almost all diffraction needs, especially when the efficiency requirements are relatively high. Diffraction gratings can be used in a variety of monochromatic research, teaching, and industrial applications. Almost all commercial spectrophotometers use diffraction gratings to select specific wavelengths or scan the entire wavelength region. Customers can select gratings according to size, groove spacing and blaze wavelength. Because the surface of the grating is aluminum film, there is no inventory in advance, but the grating can be quickly copied according to customer requirements.
