Vacuum Spectrometer for UV Imaging

McPherson, Inc. has announced the release of their new “Vacuum UV Imaging Spectrometer.” This spectrometer adds the capability to work deep into the Ultraviolet, to less than 120nm! It provides the useful combination of vacuum-compatible fabrication, high reflectivity optical coatings, and the capability to provide high-resolution spectra and spatial imaging. These are potentially useful features for researchers and experimentalists studying atomic spectra from high temperature plasmas, astrophysics observations, images of the solar disk and solid state samples.

The new vacuum spectrometer features stainless steel housings and components for ultra-high-vacuum applications. The instrument readily achieves 10E-6 torr vacuum during operation with elastomer (Viton™ or Buna-N) seals. Full featured models have master polished optics, multiple entrance and exit port locations and high precision wavelength drives for excellent wavelength reproducibility. Specialized high reflectivity coatings provide up to 78% reflective efficiency at wavelengths as short as 120nm, other coatings are available for peak performance in mid-wave and long-wave-infrared applications. An aggressive f/4.7 aperture ratio (670mm f.l.) assures excellent light throughput.

Fitted for wavelength scanning and imaging applications the McPherson vacuum spectrometers readily accommodate many commercial back-thinned, windowless 2D CCD and CMOS sensors and many single channel Silicon diode or scintillated photomultiplier type sensors. Most popular, the two-dimensional sensors allow users to collect more information in half the time. Sub-nanometer high-resolution spectra and discrete spatial information from the source are collected simultaneously. These are ideal instruments for experiments involving transient or fast plasma physics, astrophysics, material science (luminescence, Raman) or laser-matter interaction experiments.

McPherson’s vacuum spectrometers are available in focal lengths of 0.67, 1.0, 1.3 and 2-meters and can be prepared for high-vacuum and also ultra high vacuum applications with all metal seals. Various vacuum compatible accessories are available, including calibration sources, detectors, sample handling accessories and more.
