DMO160 is a high-aperture double monochromator with dispersion subtraction. It is an instrument with F-number of 3.5 and input focal length of 160 mm.
The wavelength tuning is motorized and controlled by PC via RS-232 interface.
The monochromator uses the optical schematic with as few as four optical components and an intermediate slit ensuring low stray light and high aperture ratio. The concave diffraction gratings with a variable lines density allow astigmatism compensation in the DMO160 double monochromator.
