  • UV-IR range variable angle spectroscopic ellipsometer
    Patent number: 8253940
    Abstract: 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.
    Type: Grant

    Date of Patent: August 28, 2012
    Assignee: J. A. Woollam Co., Inc.
    Inventors: Steven E. Green, Gerald T. Cooney, Martin M. Liphardt
  • Spectrophotometer, ellipsometer, polarimeter and the like systems
    Patent number: 7327456
    Abstract: Disclosed are improvements in ellipsometer and the like systems capable of operating in the Vacuum-Ultra-Violet (VUV) to Near Infrared (NIR) wavelength range, and methodology of use.
    Type: Grant

  • Sample entry purge system in spectrophotometer, ellipsometer, polarimeter and the like systems
    Patent number: 7274450
    Abstract: A sample sequestering system which allows access to a subspace in a chamber encompassed generally enclosed space, for use in entering and removing a sample when the subspace is opened to atmosphere. Sufficient purge gas is flowed from within the generally enclosed space into the subspace discourage atmospheric contaminates from entering into the subspace. Contained within the generally enclosed space is a spectrophotometer, ellipsometer or polarimeter or the like system which operates at wavelengths, (eg. UV), which are adversely affected, (eg. absorbed), by typical atmospheric contents.
