A typical diffraction grating has thousands of grooves per millimeter on the reflective surface of a plate that can be flat or curved. Different gratings cover various electromagnetic radiation ...

The period and strength of the index change effectively defines the grating's optical properties, in particular the strength and wavelength of its reflection. Gratings are usually designed to oper ...

High performance reflection and transmission gratings manufactured via ultra precise DUV photolithography. Every grating a master, high volume, low cost. Transmission gratings exhibit tenth dB PDL and ...
