Gratings with 750 nm to 1600 nm Blaze Wavelengths

High Grating Efficiency of 60 to 80% at the Blaze Wavelength

Low Ghosting, <0.5% of Parent Line

Aluminum Reflective Coating

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.
