This Feedthrough Type BL 340 is provided for mounting of slit systems and collimators.
BL 340 allows for a symmetrical opening and closing of a slit system perpendicular to beam axis. It is mounted on a CF-100 flange (or larger). The translation is performed by means of two (2) spindles, driven by a D.C. motor or a stepping motor. The exact symmetry of the displacement of the two slit jaws is performed by using two spindles with right and left threads, respectively. Sealing is accomplished by membrane bellows. Measurement of position will be possible via a 20-turn potentiometer or encoder (optional).
