Soda Lime Glass Substrate with 300 to 1200 Grooves/mm
Seray offers ruled diffraction gratings for use in the near-IR region. These gratings will have a relatively sharp efficiency peak about their blaze wavelength 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.We also offer reflective holographic gratings, which do not produce ghosting effects at the expense of efficiency.
