Monochromator
In the dual echelle monochromator, the prism monochromator acts as a preselection
system to select the required wavelength range to pass on to the echelle
monochromator. Optimally positioned slits and baffles result in very low stray light
levels reaching the echelle monochromator. The prism and echelle dispersion
systems use Littrow configurations, designed to eliminate astigmatism, with
identical, 300 mm focal length, 10° off-axis, parabolic, collimating and focusing
mirrors.
The echelle grating has 79 lines/mm with a blaze angle of 63.4°. The grating is used
in the higher orders, where the high efficiency and high dispersion allow a relatively
short focal length resulting in a compact optical system.
