Planar equally spaced grating monochromator (PGM)

Planar equally spaced grating monochromator (PGM) adopts an optical system based on C-T arrangement. Through the switching of two gratings and ultra-high-precision grating scanning function, it can distinguish different wavelength beams. The system has ultra-high precision and repeatability. and stability, and has been widely used in beam lines of synchrotron radiation sources.
