    Abstract: A shutter assembly (12) comprising a first planar member (70) and a second planar member (72) opposed from one another and forming a sleeve having a cavity (80) therebetween, the sleeve having a pair of side rails (78) adjacent the cavity along sides of the sleeve. A first shutter member (14) having a first end (92) is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member (14) having a second end (92) is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture (15) therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions. The shutter assembly is well suited to be used at a cryogenic temperature and in a high vacuum environment.

    Abstract: An apparatus (100) includes a first component (102) having a first surface (106) and a second component (104) having a second surface (110). The first surface includes sputtered gold, and the second surface includes a stainless steel alloy. The first surface is configured to contact the second surface, and one of the components is configured to move against another of the components. The stainless steel alloy could consist of a UNS 21800/AISI Type S21800 metal. The sputtered gold could include ion sputtered gold, and the sputtered gold could have a thickness of about 1 micron. The first component could include a first blade (306) of an adjustable aperture mechanism, where the adjustable aperture mechanism also includes a second blade (308). The second component could include a first plate (310) of the adjustable aperture mechanism, where the adjustable aperture mechanism further includes a second plate (312). The blades can be configured to move within a space between the plates.
