Systems for Spectroscopy Raman Workstation The McPherson Raman Workstation is a complete spectroscopy solution. It is available optimized the popular laser lines from 224 to 1,000 nm. For shorter ultraviolet wavelengths or when tuning is desired, the novel McPherson prism pre disperser may also be a sharp cut filter. Systems include a solid-state laser, specialty filters, and a sample chamber with focusing and collection optics. They are also available with a sample chamber cryogenic sample holders for photoluminescence (PL) work.

UV Raman Triple Spectrometer Enhanced UV response and more throughput with an open architecture set the Commander™ apart. This triple-spectrometer works from deep UV to Infrared with a selection of diffraction gratings. It operates at an impressive f/5. It delivers edge rejection within 5 cm-1 in the visible region. This instrument is free from chromatic aberrations. Aspheric mirrors correct and improve imaging performance for excellent signal levels at the detector, even with weak samples.

Spectral Calibration and Test Station McPherson's new Spectral Test Station provides a 100 mm 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. The Spectral Test Station (STS) delivers discrete bands of selected monochromatic light and/or scans selected spectral regions in the 185 nm to 14um LWIR wavelength range – and more. Up to four turret mounted gratings (Model 205wr) assure efficient coverage of wide spectral ranges. The gratings "snap-in" feature permits to easily replace gratings or add broad or narrow band reflecting mirrors. This provides means for testing sensors and detectors with integrated as well as spectral light. The system is especially useful for QC testing of multiple detector chips, CCDs or focal plane arrays in a given wavelength range and for given pixel responsiveness.

Systems for Spectroscopy VUVAS Spectrophotometer McPherson has launched its latest VUVAS high-performance, scientific grade spectrophotometer. McPherson’s new measurement platform provides more stable measurements over time and is easier to maintain. With longer lamp life at short ultraviolet wavelengths (120nm), it’s ideally suited to analysis of doped and crystalline materials, as well as deep UV optics and coatings. The new VUVAS offers direct optical characterization of transmission, and variable angle reflectance.

It also offers precise, reproducible wavelength control throughout the 120 to 350 nanometer wavelength region.

VUVAS-PLus

Optical properties and Luminescence The new VUVAS PLUS Spectrophotometer system works from 115nm vacuum ultraviolet to 1800nm infrared. The new system measures transmittance and reflectance at adjustable angles.

Plus, it delivers tunable vacuum ultraviolet (VUV) excitation light to samples with emission measured in the visible and near infrared. A high vacuum environment keeps samples clean and prevents absorption by atmospheric gases and water vapor. A closed cycle liquid Helium cryostat allows cooling samples during measurements too.

Vacuum Ultraviolet Optical Characterization System This Vacuum UV Spectrophotometer is designed for Transmission, Reflection and Emission measurements across a broad wavelength range.

The system has a range of 115nm to 930nm that can be expanded into the Extreme UV or into the IR. The interchangeable sample holder(s) accept five samples that can be indexed under vacuum.

The optical, electrical and pumping systems are built into the support table for easy transport and set up

Systems for Spectroscopy Imaging Spectrometer New reflective correction optics for spectroscopy imaging applications with two dimensional CCD or CMOS type sensors now available for McPherson’s high resolution, one meter focal length spectrometers. Equipped with select accessories, the McPherson spectrometer can simultaneously monitor spectra from one hundred input fibers on one commercial 1024*1024 pixel, ~13mm square CCD. The one meter spectrometer accepts various Snap-In™ diffraction gratings optimized for spectral resolution or for wavelength range coverage.

Vacuum Ultraviolet Luminescence To develop vacuum ultraviolet excitable phosphors the Institute of Low Temperature and Structure, Polish Academy of Science contracted McPherson to build a characterization system for the 120nm to 1800nm range. This system measures and characterizes luminescence of phosphors and crystals.

It is hoped that the benign discharge of a noble gas will replace Mercury excitation, for phosphor excitation under environmentally acceptable conditions. The research is intended to help create more efficient methods of commercial lighting.

Today’s compact fluorescent lamps (CFL) often still use Mercury, harmful to humans and nature. The new VUV phosphors are instead excited by environmentally benign discharge in noble gas. The VUV phosphors will be twice as energy efficient as today’s CFL’s.
