This item is a Zygo 7001 Beamsplitter cube with a 50% reflectance. It is completely interchangeable with the Hewlett-Packard type 10701A beam-splitter. The only difference between them is the scallop out of the opposite sides of the beam-splitter to reduce mass. The cube has a beam-splitting reflector set at 45-degrees and face-centered to three adjacent faces. The mirror surface is coated. These components are useful when it is desired to have two axes tied to a single laser (each axis will require its own interferometer and detector, however).

The angle of the beam-splitter is not critically set within the cube in order to keep component prices reasonable. For precise positioning it is recommended that the beam-splitter is fixtured using a small leveling base (HP 10710A or equivalent). These mounts allow for corrections in two directions. Pitch may be adjusted through several degrees about the axis of the mirror component by resetting the cradle position in the base, and yaw may be adjusted using the play in the elongated slots for securing the base. The base of the mount has an open aperture so the beam path may be directed through the base of the fixture

These components have been removed from various fixtures. They meet our requirements for second quality used interferometer components. All optical surfaces are free of serious 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 in very fine condition, although not new. Unlike new components, no hardware is included.
