Gratings should only be handled when necessary and always held by the sides. Latex gloves or a similar protective covering should be worn to prevent oil from fingers from reaching the grating surface. No attempt should be made to clean a grating other than blowing off dust with clean, dry air or nitrogen. Solvents will likely damage the grating's surface.elength and are produced from ruled originals. They are offered with different blaze angles to suit a variety of applications in spectroscopy and analysis where high efficiency is of primary concern. |
Reflection Gratings
Reflection gratings are precision diffractive optical elements operating in reflective mode. Relying on periodic micro-nano groove structures on their surfaces, they realize polychromatic light dispersion, wavelength filtering and beam steering via light diffraction and reflection. Capable of dispersion without a transmission light path, they feature compact structures and flexible optical layout, serving as fundamental core dispersive components widely adopted in spectrometers, laser systems and high-precision optoelectronic equipment.
