April 2008 - VUV Optical Characterization System: McPherson, Inc. received a contract from the Optical Crystals group in the Solid State Physics Division of the Institute of Physics and Academy of Science (Czech Republic.) Under the contract, McPherson fabricated and delivered a vacuum ultraviolet spectrometer system to measure and characterize the optical and luminescence properties of optical crystals, films and single crystals (alkali halides, microcrystalline precipitates.)
March 2008 - Vacuum Ultraviolet Light-Source, 30nm+ The McPherson vacuum ultraviolet, hollow-cathode light source suitable for wavelength calibration, ultraviolet photoemission spectroscopy (UPS) and other vacuum ultraviolet spectroscopy applications. This continuous gas-discharge lamp is used with inert molecular or rare gases.
February 2008 - Vacuum XUV Spectrometer, 10 to 1000 eV, Model 248/310, for work through the vacuum ultraviolet including the extreme UV (XUV) and soft x-ray wavelength regions. It comes with vacuum tight seals for the 10-6 torr vacuum region. Research worldwide for attosecond laser pulses, compact extreme ultraviolet lasers and high harmonic lasers generation benefit from McPherson spectrometers ability to quickly and accurately provide XUV wavelength information.
January 2008 - McPherson delivers very High-Resolution-Raman-Spectrometers featuring 2m focal length, large masterpiece reflective optics used for spectral agility and wide-wavelength-range optical performance. Unique focal plane formation covers about 12" in wavelength space. Spectral resolution of about 10 to 15 picometer full width half maximum is attained totally across the large focal plane.
September 2007 - McPherson's new Spectral Test Station provides a 100mm diameter collimated and wavelength variable monochromatic light beam to illuminate, spectrally calibrate and document radiometric sensitivity and response characteristics of spectral and hyper-spectral sensors.
July 2007 - Optical / mechanical components for ultraviolet applications requiring clean inert purge, vacuum or ultra high vacuum environments. Customer specified, made to order components and standard beam delivery accessories include simplified grating actuators, mirror mounts, optical choppers and polarizer mounts. These items are available or o-ring sealed construction for purge applications and vacuum applications to the 10-6 torr range. All elements are clean and ready for vacuum use. They are contaminant free and Helium leak checked.
March 2007 - 'Hubble's Helpers' - McPherson vacuum ultraviolet monochromator systems help calibrate Cosmic Origin Spectrograph. McPherson instruments helped calibrate space flight systems for the Chandra X-ray Observatory and the Space Telescope Imaging Spectrograph (STIS.) Now they are called to work on the Hubble Space Telescope's new eye in the ultraviolet, the Cosmic Origin Spectrograph (COS.)
March 2007 - Thermally controlled aperture and slit systems for high performance monochromators and synchrotron monochromator beam lines utilize extremely precise, adjustable and actively cooled apertures for entrance occulting and dispersion controlling slits and masks.
February 2007 - McPherson VUV spectrometer system to diagnose the tokamak fusion plasma at HL-2A Tokamak at the Southwestern Institute of Physics. The Model 225 VUV spectrometer is equipped to allow novel experiments in simultaneous spectral and spatial data collection.
January 2007 - Detect laser harmonics from 4eV to 1.2keV with the McPherson, Inc. Model 248/310G. Charge coupled detectors (CCD) or alternately, gated microchannel plate (MCP) intensifiers, are preferred detection schemes. Tune wavelengths from ~1 to 300nm. Clean stainless steel construction and compact design ideal for work with laboratory discharge light sources and detectors, and astrophysics calibration work.
October 2006 - 642 x-ray source - filament electron source accelerated towards a solid anode target by high voltage. Electrons impact the solid target (anode) causing excitation of the atomic inner shells with subsequent decay and emission. The output emission spectrum of the source follows the target anode material valence band structure.
August 2006 - The McPherson Raman Workstation - a spectroscopy solution. An ideal tool for the novice; it provides everything required when starting work with the Raman technique. Experienced researchers and changing analytical goals benefit from the Workstation's open architecture.
August 2006 - InFocus Newsletter - a PDF version of the 2006 Newsletter.
March 2006 - Multiple pass monochromators are ideal for experiments where more spectral resolution is required and lab space or budget cannot accommodate a physically larger instrument. The multiple pass monochromator is useful for reaching twice the resolution or dispersion with very aggressive f/number and excellent light throughput.
