Beschreibung :

3-061H serie are holographic replicated gratings with 1000 grooves per mm, a dispersion of 0.99 mrad at 250nm.

The substrate for a holographic grating is coated with a photosensitive (photo resist) material rather than the reflective coating used in ruled gratings. Since holographic gratings are produced optically, groove form and spacing are perfectly consistent. Holographic gratings are, therefore, free from the periodic and random spacing errors responsible for ghosts and stray light in ruled gratings. The result is that holographic gratings generate much less stray light than ruled gratings.
