  • Gratings


We supply  a wide range of optical diffraction gratings with the conventional ruling technique and interference lithography from best of manufacturers all over the world.

The benefits of holographically produced gratings are high diffraction efficiency, even in high groove frequencies and very low stray light in combination with gratings on flat, concave, convex, aspherical and free form substrates.

Sinoidal, lamellar and blazed gratings can be provided for high detection sensitivity even for low-intensity signals.
