Diffraction Grating

NILT offers standard diffraction grating stamps in nickel with linear gratings or crossed gratings. The grating profile is sinusoidal. The pitch of the gratings is in both cases 500 nm and the average depth of the gratings is 250 nm. The size of the stamps is 100 mm x 100 mm with a guaranteed active area of 80 mm x 80 mm.

The standard diffraction grating stamps can be delivered with or without anti-sticking coating.

Note that the standard diffraction grating stamps are only for test and product development purposes. A commercial use of the standard diffraction grating stamp lens structures requires a royalty agreement.
