February 2018 - 5-ways to improve UV spectroscopy Vacuum UV monochromator for analytical and diagnostic applications For applications like HHG spectroscopy, plasma diagnostics, vacuum ultraviolet optical characterization, metrology and calibration the Model 234/302 meets the challenge. This research grade spectrometer has uncompromising performance. It is our pleasure to deliver components as well as system-level solutions. The Model 234/302 is also available for ultra high vacuum (UHV), metal-sealed, 10E-10 Torr applications. Call or email today to learn how the Model 234/302 fits into your experiments.

December 2017 - Triple spectrometer for Raman Raman shift 4cm-1, tunable, deep UV response, stigmatic Materials Research Forum is managed by Thomas Wohlbier McPherson triple monochromators work fast as f/5 with rejection edges down to 4cm-1. That’s more light gathering power and tighter edges than other spectrometers. McPherson’s reflective designs are tunable reaching the deep UV, 190 nanometers or less if necessary. For ultimate throughput, we offer astigmatic optics too. Check out McPherson singles and triples, well equipped for Raman, photoluminescence, and Thomson scattering
Thanks to Materials Research Forum and Thomas Wohlbier for spreading the word about unique tools for material research and spectroscopy!

November 2017 - Direct detection CCD + Software measuring short wavelength spectrum from 30 to 550 nanometers There is a whole new way to communicate with McPherson spectrometers! New and many legacy McPherson instruments can now be addressed and controlled by a new Add-In for Princeton Instruments' powerful 64-bit LightField software. This new software allows users to keep all the benefits of LightField while controlling wavelength of McPherson deep UV and soft x-ray spectrometers. This integrates Princeton's premier scientific CCD detectors with McPherson's high performance spectrometers - a boon for spectroscopy researchers worldwide.

October 2017 - Imaging spectrometer for VUV measuring short wavelength spectrum in two directions The newest McPherson vacuum ultraviolet imaging spectrometer measures very short wavelengths of light as emitted from hot plasma, synchrotron storage rings, or free-electron and high-harmonic lasers. This instrument has a specially designed optical path allowing it to measure (vertical) spatial profile in addition to (horizontal) dispersed wavelengths. It operates under high vacuum 10e-6 mbar and is available with all metal seals for ultra high vacuum too. Instruments like this are working to solve the magnetically confined thermonuclear fusion riddle at research facilities like HL-2A and superconducting EAST in China.

August 2017 -
High-energy UV lamp windowless gas ionizaion uv lamp for calibrating spectrometers McPherson is pleased to announce new and improved stability with flow controlled McPherson windowless, hollow cathode UV lamp Model 629. This broad-spectrum source emits ionized gas emission lines with little or no absorption by neutral gas. Computer controlled gas flow and constant current power supply improve stability for better spectroscopy. The Model 629 windowless, hollow cathode source is useful for wavelength calibration and other experiments at emission wavelengths from double ionized Helium (30nm) and above.

May 2017 - Visit McPHERSON at ICOPS! 44th International Conference on Plasma Science (ICOPS 2017) at the Harrah's Resort Atlantic City. May 21-25, 2017 Just three weeks to go! Stop by the McPherson exhibit! The 44th IEEE Int'l Conference on Plasma Science (ICOPS 2017) is May 21-25 at the Harrah's Resort in Atlantic City, New Jersey. More about high resolution spectrometers useful for optical velocity, rotation and temperature measurements along with vacuum ultraviolet and soft x-ray models for high energy emission line survey and detection/monitoring.

February 2017 - New High Vacuum Spectrometer stainless steel housing high vacuum monochromator for calibration and spectroscopy The new McPherson Model 207V (PDF data sheet)is an important part of deep-UV and VUV imaging and analytical spectroscopy systems. It works over a broad spectral range, from the deep UV, through the Visible into the long-wave Infrared. Its clean construction is ideal for contaminant free purge and vacuum applications. The Model 207V is a 670mm focal length optically fast f/4.7 monochromator with a vacuum tight housing. Stigmatic performance with off axis parabolic optics is available for the 207V too. With stainless steel housing capable of 10E-6 torr vacuum, this instrument works unfettered over a very wide wavelength range. Depending on the grating(s) installed it can go from 110 nanometers to 15 microns! The vacuum construction is useful for deep ultraviolet AND also for the Infrared. Vacuum removes atmospheric constituents (gas or vapor) that absorb light wavelengths in both spectral regions.

January 2017 - Deep UV Polarization rotatable UHV double monochromator for non polarized short wavelength light testing We are pleased to announce the newest McPherson vacuum ultraviolet spectral test system VUV-STS. This novel instrument measures optical reflectance as a function of angle of incidence. It can help determine optical constants. It is specially built to work with non-polarized light (!) in the 30 to 160 nanometer wavelength region. This new twist from McPherson helps users test materials, multilayers and coatings “at wavelength" for applications like attosecond spectroscopy and HHG, optical design for space applications, wavelength calibration, and thin-film / coating technique design.

November 2016 - New High Brightness Monochromator McPherson 207A stigmatic monochromator with 670mm focal length, and optically fast f/4.7 The new Model 207A is a 670mm focal length optically fast f/4.7 monochromator. It is now available with off-axis parabolic optics. The off-axis parabolic (OAP) mirrors provide low f/number and stigmatic monochromator performance. Stigmatic monochromators provide coincident sagittal and tangential foci for perfect collimation and focusing. These highly polished OAP mirrors have smooth surfaces (not diamond turned) and are well suited for work in the deep UV and even the vacuum ultraviolet region. The Model 207A preserves high brightness with no chromatic aberrations! Read more
