Zusammenfassung:An ellipsometer, polarimeter, reflectometer, spectrophotometer or scatterometer system for use in the UV and infrared range of wavelengths, characterized by the combination of a fiber optic capable of transmitting wavelengths from below 2.2 micron up to at least 3.5 microns, and a beam collimator formed from a combination of two off-axis concave astigmatism reducing spherical mirrors capable of operating between about 190 nm up to 5.5 microns.
