Purged Ultraviolet Spectrometer

McPherson has launched its latest VUVAS range, 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, variable angle reflectance, and gas cell absorbance (optional). It also offers precise, reproducible wavelength control throughout the 120 to 350 nanometer wavelength region, and sensitive signal recovery with “lock-in” detectors controlled from software. McPherson Spectrometer Control Software provides single-point control for scanning and data acquisition.

As part of the VUVAS family, corrected and single beam instruments are available with environmental controls (vacuum or the new purged versions). The new VUVAS controls give more rapid and reproducible measurements in an environment that minimizes sample contamination while extending lamp life -- through the use of purge controls that integrate sensitive Oxygen sensors and automatic low- and high-flow purge gas channels.

The VUVAS provides a very powerful tool for direct optical measurements from 120 to 350 nanometers. Many accessories are also available -- such as light sources, detectors, sample chambers, etc.

McPherson (Chelmsford, MA USA) manufactures a wide variety of instruments that measure wavelengths of light, and has served international and domestic customers in university and research laboratories for more than fifty years.
