• 750 nm Blaze Wavelength
• Aluminum Reflective Coating
• Low Ghosting, <0.5% of Parent Line
• Soda Lime Glass Substrate
• Produced from Ruled Original

This ruled diffraction grating is optimized with a blaze wavelength of 750 nm. Ruled gratings are ideal for applications centered at the grating’s blaze angle. The grating will have a relatively sharp efficiency peak about the blaze wavelength. Ruled gratings typically offer higher efficiencies than holographic gratings, while holographic gratings do not produce ghosting effects.

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 that blowing off dust with clean, dry air or nitrogen. Solvents will likely damage the grating’s surface. Scratches or other minor cosmetic imperfections on the surface of a grating do not usually affect performance and are not considered defects.
