Monochromator

The plane grating Zeiss SX-700 monochromator has 2 gratings - 1200 and 250 lines / mm. The 1200 lines / mm is the default. The monochromator can be operated at three C values, with a corresponding exit slit position (see table). Increasing the C value gives better resolution with worse 2nd order suppression, whilst lowering the C value does the opposite. C = 2.25 is the most commonly used and gives the 'best' compromise of flux, resolution and 2nd order rejection.

Resolution determined at 400.5 eV (N2) by absorption with a gas cell. The exit slit width was 5 microns.
