M11-D is a dual monochromator. The outlet of the first monochromator is the inlet of the second monochromator, and these two independent monochromators act as dual filters of scattered light, almost equivalent to the square times of the monochromator's filtering. M11-D is a dual monochromator that can be configured for addition or subtraction mode propagation. In addition mode, the first grating diffuses the beam within a certain angular range, while the second grating doubles the diffusion. As a result, the resolution of this monochromator is twice that of a 1/8-meter monochromator. In subtraction mode, the first monochromator uses the selected spectral bandwidth, while the second monochromator removes the time and angle distortions caused by angular diffusion in the first monochromator.
M11-D provides a solution for clear imaging of monochromators. Ordinary monochromators fail to produce clear images mainly because the bandwidth formed by multiple wavelengths can cause multiple, overlapping images. In M11-D, the second negative monochromator recombines these multiple images to form clear images, and M11-D is also a unique solution for pulse source spectroscopy. A typical monochromator increases the optical pulse width by 25 to 100 picoseconds during the transmission process with a fixed optical path length inside, while in the M11-D subtraction mode, the second monochromator compensates for the optical path length to minimize the optical pulse width.
