This item is an HP 10702A Linear Interferometer with one HP 10703A Retroreflector attached. No converter window or second reflector is included. This is the basic interferometer in the 1.5� cube factor. It consists of a polarizing beam-splitter and the corner-cube reflector. One interferometer and one detector are required for each axis in the Hewlett-Packard Laser Interferometer Distance Measurement Apparatus.

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 large leveling base (HP 10711A). 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 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. Unlike new components, however, no hardware is included.

HP 10715A Differential Interferometer

HP 10715A Differential Interferometer, new in the original packing. It is one of the more elaborate interferometers using the 1.5� cube form factor. These components belong to the Hewlett-Packard Laser Interferometer Distance Measurement Apparatus. The interferometer includes a special diagonal beam-splitting window which I have not figured out � it may be some sort of phase shifting plate to turn the plane of polarization. The interferometer includes a special magnetic target disk used in the initial setup of the device. It includes two retroreflector modules and a converter window, but attached to the opposite side from the converter, is another module with a right-angle beam-splitter with two exit ports on each side, marked �A� and �B�. There appears to be a quarter-wave plate between the main interferometer body and the second beam splitter. I have no idea how the diagonal mirror is used. . .

Slight chip on unused portion of the reference mirror.

Again, this is new in the box. I believe this component would benefit from the use of the large leveling base (HP 10711A). The only mounting faces are the opposite sides of the main interferometer body.

HP 10702A Linear Interferometer with Options 001

This item, while missing the original HP label, has been identified as a type 10702A Linear Interferometer. The interferometer body has been scribed with the original beam-path schematic diagram found on the original label. This is one of the �medium-sized� components in the Hewlett-Packard Laser Interferometer Distance Measurement Apparatus. The central cube is 1.5� square. On one side of the beam-splitter is a type HP 10703A Retroreflector, and on the opposite side, a type HP 10724A Plane Mirror. This interferometer is equipped with the Option 001 � a type HP 10722 Converter Window. None of the components have the original labels.

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 large leveling base (HP 10711A). 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. Beams should ONLY be deflected at right angles in each laser / detector assembly in order to avoid depolarization of the laser beams.

These components have been removed from various fixtures. They have been classified as second quality because of the missing labels as well as the rather crudely scribed schematics. 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 in very fine condition, although not new. Unlike new components, no hardware is included.
