HP 10706A Plane Mirror Interferometer
$275.00This item is an HP 10706A Plane Mirror Interferometer, but it is lacking the reference mirror component (HP 10724A). This item is one of the �medium-sized (1.5� cube)� components in the Hewlett-Packard Laser Interferometer Dimensional Measurement Apparatus. The interferometer ordinarily consists of several assemblies. The cube assembly (present here) is a beam-splitting interferometer, type 10706A, which consists of a beam-splitter cube that plane polarizes the light. On either side of the cube would be mounted a type HP 10703A Retroreflector. The further addition of an HP 10722A optical wedge would allow the receiver to move relative to the interferometer body. The laser is on the opposite side from the receiver.
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 meet our requirements for second 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 do have some minor issues. Some of the dress plastic baffles that are inset into the steel frames are absent, and there are some minor scratches in the steel frames. No hardware is included with the interferometer body.

Small Leveling Fixture
$45.00Small Leveling Fixture for laser interferometer.
We are 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, we doubt it is of any consequence. The main advantage in this base is in the degree of control.

HP 10702A Linear Interferometer 1st Grade
$225.00This item is an HP 10702A Linear Interferometer with one HP 10703A. Retroreflector and one HP 10722 Converter Window attached. A second reflector is not 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 addition of the compensating converter window allows a second retroreflector to move relative to the fixed interferometer body..
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.

HP 10715A Differential Interferometer
$1,200.00HP 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 Options
$350.00HP 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.

HP 10565A Remote Interferometer
$450.00This is an HP 10565A Remote Interferometer. It is one of the major components in the Hewlett-Packard Laser Interferometer Measurement System. It is based on the larger 2� cubes, and uses a 1.4� square bolt pattern for mounting. The interferometer includes the matching retroreflector (HP 10556A). The remaining three entry / exit faces of the cube appear to have � lambda plates installed within them. I believe this is the standard configuration for the interferometer. No other reflectors (retro- or mirror) are included.

Tropel 9000 Laser Interferometer
This is a Tropel Model 9000 laser interferometer. It is used for checking the flatness of wafers and masks up to 5 inches in diameter. It uses a HeNe laser as a monochromatic source, and has a built-in video camera for fringe display on a Sony Black & White monitor.
The interferometer is in spectacular condition with the exception of a small scratch near the upper center of the reference prism (outside the field of view of all but the largest wafers). The wafers are held in place by a vacuum chuck and fringe spacing and direction is adjusted via three very fine setting screws located to either side and beneath the chuck holder.
The interferometer includes the following chucks:
� 2 inch vacuum chuck
� 3 inch vacuum chuck
� 4 inch vacuum chuck
� 5 inch ‘bow’ chuck***MPN Model 9000
