Options
252	Programmable filter wheel mounted just inside the entrance slit
SAM	Remote operated swing-away mirror , can be fitted at entrance or exit (or both) where it can be used with a second slit or, in the case of the exit, with slit and array. Order sorting cannot be implemented at the alternative entrance slit, but the SAM is still useful for light sources not requiring order sorting, eg deuterium
MVSS	Motorised slit, allows software control of slit width and hence operating bandwidth
FF	Fine focus, puts the focusing mirror on a translation stage and is a must for arrays. The FF option allows you to move the focal plane up to 25mm outside the monochromator housing to fine focus on the array surface
