The Zygo research team is committed to publishing their latest research in the scientific and optical metrology communities.
This article discusses the general purpose of the laser diode mount described here avoids at least some of these difficulties by using an angle-polished fiber cable and an inexpensive coupler based on a small tip/tilt stage. The mount is very stable, can be used with a variety of lasers, and is inexpensive to make.

This article discusses the radius of curvature is a fundamental parameter of optical surfaces. Improving the measurement tolerance is critical for an increasing number of applications. Interferometry is potentially a very accurate technique, but careful implementation is critical to achieving full potential.
