Product Description
I am not sure of the manufacturer of this device, but it is very similar in function and size to the HP 10710A Small Leveling Base. It would be used to fixture components using the 1-inch cube factor. This base differs in several respects, however. Instead of using a cradle with a goniometer type motion, this base is hinged on one side using a spring steel blade. There are a pair of set screws which are then used to tip the plate very precisely. They can, in turn, be secured with a pair of adjacent Allen cap screws. This system would allow much finer control of the pitch of the attached device. Yaw may be adjusted using the ample slots in the base. The degree of pitch available is much smaller than that provided by the 10710A, and the component will not remain ‘face-centered’ as it is adjusted. However, due to the small amount of motion provided, I doubt it is of any consequence. The main advantage in this base is in the degree of control.
These components have been removed from various fixtures. They meet our requirements for first quality used interferometer components. All optical surfaces are free of blemishes and there are no gouges or distortions in any of the parts that would in any way impede accuracy of measurements. Cosmetically these components appear only lightly used, if not new. These bases include a pair of mounting screws along with a pair of elongated plates to cover the slot in the base.
