  • Ultraviolet Spectrometer

Mar 2010
McPhersonRequest Info
McPherson Inc.’s vacuum ultraviolet (VUV) spectrometer is now available with sensitive, cooled, scientific-grade CCD detectors. Model 234/302 is suitable for plasma process mapping, fluorescence, luminescence and VUV photoemission applications. The compact, 200-mm-focal-length instrument features adjustable slits and operates at f/4.5 to deliver fast, sensitive data collection from ultraviolet radiation and emission spectra in the 100- to 190-nm range simultaneously, in near-real time, with subnanometer spectral resolution. It is compatible with many models of cooled, back-illuminated and windowless sensors and is available with standard light sources, reflective condenser optics and vacuum differential sections.

1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
See fluorescence; phosphorescence.
The emission and/or propagation of energy through space or through a medium in the form of either waves or corpuscular emission.
1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
