ENERGY SELECTING SLIT AND ENERGY SELECTIVE SAMPLE ANALYSIS SYSTEMS UTILIZING THE SAME

摘要

A device comprising an energy selecting slit assembly (10) is provided. The slit assembly comprising a slit assembly chassis (20), opposing slit mechanisms (30, 40), and an actuator assembly (50). One of the terminal ends of the actuator arm comprises a relatively fixed terminus (52a), while the other terminal end of the arm comprises a relatively mobile terminus (52b) coupled to the rotational slit mechanism (30) via a mechanical coupling (60) configured to translate movement of the mobile terminus into rotational of the rotational slit mechanism. In one embodiment of the present invention, the slit assembly chassis defines a plurality of fixturing datums (22, 24) configured to establish alignment of respective aperture-defining edges (35, 45) of the opposing slit mechanisms along orthogonal X, Y, and Z axes defined by the chassis. Additional embodiments are disclosed.
