CHELMSFORD, Mass., Sept. 30, 2011 — Vacuum spectrometers are now available from McPherson Inc. for vacuum ultraviolet applications involving transient or fast plasma physics, astrophysics, materials science (luminescence, Raman) and laser-matter interaction experiments.
The vacuum spectrometers feature stainless steel housings and components for ultrahigh-vacuum applications. They achieve 10E-6 torr vacuum during operation with elastomer (Viton or Buna-N) seals. They have master polished optics, multiple entrance and exit ports, and high-precision wavelength drives for good wavelength reproducibility.
High-reflectivity coatings provide up to 78% reflective efficiency at wavelengths as short as 120 nm, and other coatings are available for peak performance in mid- and long-wave-infrared applications. An f/4.7 aperture ratio (670 mm, f/l) assures good light throughput.
Suitable for wavelength scanning and imaging applications, the spectrometers accommodate many commercial back-thinned windowless 2-D CCD and CMOS sensors and many single-channel silicon diode or scintillated photomultiplier ones. The 2-D sensors allow users to collect more information in half the time. Subnanometer high-resolution spectra and discrete spatial information from the source are collected simultaneously.
Available in focal lengths of 0.67, 1, 1.3 and 2 m, they can be prepared for high- and ultrahigh-vacuum applications with all metal seals. Available vacuum-compatible accessories include calibration sources, detectors and sample handling accessories.
