HP 10715A Differential Interferometer

The HP 10715A performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long-term stability. The HP 10715A minimizes deadpath, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The HP 10715A Option 001 is available for optical layouts that require the interferometer to turn the beam.

The HP 10715A is part of a family of interferometer systems that can be tailored for the physical layout and measurement requirements of individual applications. Configured with appropriate laser head and system electronics, HP optics products compose precise positioning systems that improve product quality, increase yields, and facilitate the manufacture of precision products.
