描述

The Agilent 10715A Differential Interferometer performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long term stability. The 10715A minimizes deadpath, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The resolution of the measurement is twice that of a linear or single-beam interferometer.

The 10715A includes three retroreflectors, a beam bender and two quarter wave plates. The user must provide both the reference and measurement mirrors.

The 10715A Option 001 is available for optical layouts that require the interferometer to turn the beam.
