摘要:
Systems and methods for providing and enhancing electromagnetic radiation beam radial energy homogeneity and intensity vs. wavelength content, for reliably directing electromagnetic radiation emitted by a source thereof in a common direction, for achromatically reducing spot size on a sample (eg. liquid cavity containing lenses and low aberration 1:1 imaging systems modified to perform as spatial filters), and for directing different wavelengths into different detectors, in ellipsometer, polarizer or the like systems.
摘要:
Disclosed are systems for, and methods of controlling radial energy density profiles in, and/or cross-section dimensioning of electromagnetic beams in polarimeters, ellipsometers, reflectometers and spectrophotometers.
摘要:
System for and Method of analyzing a sample at substantially the exact same small spot thereon with a plurality of wavelengths using a lens system which provides the same focal length at at least two wavelengths at various positions thereof with respect to a sample, including analyzing data obtained at those wavelengths.
摘要:
Disclosed are system for and method of analyzing the substantially the exact same point on a sample system with at least two wavelengths, or at least two ranges of wavelengths for which the focal lengths do not vary more than within an acceptable amount.

Disclosed are system for and method of analyzing the substantially the exact same point on a sample system with at least two wavelengths, or at least two ranges of wavelengths for which the focal lengths do not vary more than within an acceptable amount.
摘要:
A substantially self-contained “on-board” material system investigation system functionally mounted on a three dimensional locational system to enable positioning at desired locations on, and distances from, the surface of a large sample, including the capability to easily and conveniently change the angle-of-incidence of a beam of electromagnetic radiation onto a sample surface.
摘要:
Disclosed is a system for enabling easy sequential setting of different Angles-of-Incidence of a beam of electromagnetic radiation to a surface of a sample system, and to regression based methodology for evaluating and compensating the effects of the presence of electromagnetic beam intercepting angle-of-incidence changing systems, including where desired, parameterization of calibration parameters.

Systems and methodology for orienting the tip/tilt and vertical height of samples, preferably automated, as applied in ellipsometer and the like systems.
摘要:
A substantially self-contained “on-board” material system investigation system for effecting relative translational and rotational motion between a source and detector of electromagnetic radiation and a sample, which system is functionally mounted on a three dimensional locational system to enable positioning at desired locations on, and distances from, the surface of a sample, including the capability to easily and conveniently effect rotation and/or to change the angle-of-incidence of a beam of electromagnetic radiation onto a sample surface and/or to provide gas flow confined in a mini-chamber near the surface of a sample, at a location at which a beam having UV, VUV, IR and/or NIR wavelengths of electromagnetic radiation is caused to be impinged thereupon.
