Motorised x-y stage


A Motorised x-y stage is available, designed for easy interchange with other specimen mounting options. The stage may be connected or disconnected at any time and simply slides into position on the base of the Reflectometer. A manual z-stage is included providing 40 mm vertical movement plus graduated manual rotation through 360. A steel platform with low-profile magnets is offered as standard, along with a special holder for mounting the glass standard. A vacuum platform is available optionally.
