• Gratings with 400 nm or 500 nm Blaze Wavelengths
• High Grating Efficiency of 60 to 80% at the Blaze Wavelength
• Aluminum Reflective Coating
• 300 to 1800 Grooves/mm
• Produced from Ruled Original

We offers ruled diffraction gratings for use in the visible region. These gratings will have a relatively sharp efficiency peak about their blaze wav

Warning

Optical gratings can be easily damaged by moisture, fingerprints, aerosols, or the slightest contact with any abrasive material. 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.
