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:
In the context of an ellipsometer or the like, positioning a camera other than directly above a sample being investigated by an electromagnetic beam, while said camera provides an optical view of a surface of said sample which is in focus over the entire viewed extent of the sample, and wherein a contrast improving system involving two beams provided by a beam splitting system is utilized.
摘要:
Computer driven systems and methods involving at least one electromagnetic beam focuser and digital light processor that in combination serve to position selected wavelengths in a spectroscopic electromagnetic beam onto a small spot on a sample, and direct the one or more selected wavelengths reflected by the sample into, while diverting other wavelengths away from, a detector.
摘要:
Disclosed is a system for controlling focus, angle of incidence and intensity of an electromagnetic beam over a spectrum of wavelengths, and methodology for optimizing investigation of samples which demonstrate low specular reflectance and/or are depolarizing of a polarized beam of electromagnetic radiation, such as solar cells.
摘要:
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.
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:
A small internal volume cell having fluid entry, and exit ports wherein at least one bubble trap is present in a fluid pathway which is continuous with the fluid exit port. There further being present an input/output aperture, for entering and exiting electromagnetic radiation, positioned to allow causing an input beam of electromagnetic radiation to impinge on a sample substrate at a location thereon at which, during use, fluid contacts; and a mirror for directing electromagnetic radiation which reflects from said sample substrate, toward and out of said input/output aperture; as well as methodology of its use.
摘要:
An electromagnetic beam chromatic shifting and directing means for use in reflectively directing a spectroscopic beam of electromagnetic radiation while simultaneously de-emphasizing intensity in a first range of wavelengths, (eg. the Visible wavelengths), and simultaneously relatively emphasizing intensity in another wavelength range, (eg. UV wavelengths).
