Book Description
The University of Dayton has designed and built an Infrared Ellipsometer/ Reflectometer (E/R) to characterize curved surfaces in support of the ALPHA Laser Program. The instrument is tunable in wavelength and angle of incidence, is remotely controlled by a dedicated microcomputer, is positioned and scanned by a six-degree-of-freedom translation stage, and makes simultaneous measurements of Rp, Rs, ?, and ?.

Book Description
The University of Dayton Research Institute (UDRI) has designed and is building three infrared ellipsometers in support of the Air Force high-energy laser program. One of these instruments is a conventional null type elliposmeter for operation in the 3.39 to 4.00 ?m wavelength range. Ellipsometric parameters are determined with a precision of 0.01° at any angle of incidence from 20° to 85°. Repeatability and absolute accuracy also approach 0.01° which yields optical constants accurate to 0.1 percent in some cases. All components are mounted on removable carriers for easy interchange, although operation is normally in the PCSA (Polarizer, Compensator, Sample, Analyzer) configuration.

Book Description
The objective of this dissertation is to present opto-mechanical design of a synchrotron radiation based far-infrared spectroscopic ellipsometer with a strong external magnetic-field capability. Since high magnetic field has enabled major breakthrough in science such instrument will be highly important to the field of condensed matter physics and characterization of advanced electronic materials. This instrument will be installed at the multi-User facility with the most advanced synchrotron light source: Natonal Synchrotron Source (NSLS-II) at Brookhaven National Laboratory (BNL).The proposed here instrument is capable to measure full Mueller matrix spectroscopic ellipsometry spectra in high magnetic fields of up to 9 Tesla. The designed instrument consists of Polarization State Generator (PSG) chamber, Spectromag optical solenoid (high magnetic field up to 9 T), cryogenic sample stage, Polarization State Analyzer (PSA) chamber, and a bolometer. The PSG and PSA vacuum chambers are separated from the magnet volume with two pairs of gate valves equipped with optical windows. This instrument is capable of using synchrotron radiation in the spectral range of 20 cm-1 and 4000 cm-1. The sample stage could operate in the low temperature range down to 4 K with an option to cool sample down to 1.6 K. This instrument allows User to switch between Faraday and Voigt configurations for external magnetic field. This ellipsometer will be able to measure the full-Mueller matrix spectra using rotating retarders and rotating polarizers.
