Optical components of non-planar geometry require special machining to produce. Single point diamond turning is the manufacturing method of choice to produce these surfaces. Three main factors contribute to the quality of these surfaces. Machine accuracy has shown improvements with the increased use of air bearings. Tool wear and design are shown to be(More)
A method is described for directly measuring the temperature of a substrate in a molecular-beam epitaxy (MBE) growth system. The approach relies on the establishment of the temperature dependence of Raman-active phonons of the substrate material using independently known calibration points across the range of interest. An unknown temperature in this range(More)
