Product Description
This item is an HP 10706A Plane Mirror Interferometer in a fitted wood cabinet. This item is a ‘medium-sized (1.5” cube)’ component in the Hewlett-Packard Laser Interferometer Dimensional Measurement Apparatus. The interferometer consists of several assemblies. The cube assembly 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 is a type HP 10703A Retroreflector. The further addition of an HP 10722A optical wedge allows the receiver to move relative to the interferometer body. The laser is on the opposite side from the receiver.
The interferometer is supplied in a nice fitted cabinet. The original urethane had completely deteriorated and has been replaced with much more stable expanded polyethylene foam. The cabinet is in very fine condition, but there is some ink writing on the top cover.
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 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.
