February 2017 - New High Vacuum Spectrometer
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
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.

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 May 2016 - VUVAS-10X Analytical Monochromator
A new ultraviolet spectrophotometer system for optical metrology just arrived at NASA Goddard! The VUVAS-10X spectrophotometer works best in the 90 to 160 nanometer wavelength range, also known as deep or vacuum ultraviolet (VUV) region. It uses a windowless hydrogen plasma light source and differential pump section to reach many wavelengths beyond those of conventional deuterium lamps. The source also works with other gases, or gas mixtures, for atomic spectral line emission from about 30 nanometers (double ionized Helium gas) up to the Visible light range. The new spectrophotometer system, McPherson VUVAS-10X, uses a one-meter focal length high-resolution monochromator with the special light source, scintillated detector and Model 121 goniometric sample chamber. The system is ideal for optical transmission, absorbance and specular reflectance at incident angles up to 60 degrees. This McPherson spectrophotometer system will help develop, inspect and qualify optical materials and coatings used for very high altitude and extraterrestrial space flight missions.

A Model 2035DS double monochromator, collimator, variable-angle sample chamber, integrating spheres and more make up the system for the National Institute of Metrology (NIMT). The double monochrometer allows users to “dial in” very pure wavelengths of light -- invisible ultraviolet to infrared. The light is sent to samples-under-test. Samples include optical materials, windows, filters, coatings, solar cells, photo sensitive detectors and so on. The McPherson system allows the users to test diverse materials with different wavelengths of light
November 2015 - Spectral Test Station for Visible, NIR and LWIR
Sensors, seekers, and digital cameras are pervasive. CCD, CMOS, InGaAs and further to the infrared, each exhibits unique response. The spectral test station delivers discreet, high purity wavelength bands to devices under test. This helps characterize the response of sensors to specific wavelengths of light in order to calibrate ...
