McPherson (Chelmsford, MA) has announced a new vacuum ultraviolet universal spectrophotometer, an optical test system optimized for emitting samples like phosphors or photo- and electro-luminescent crystals. It can measure reflectance, transmission and fluorescence emission over its complete working range, 120 nanometers to 2.2 microns. The sample chamber includes high efficiency toroidal optics for focused excitation and sensitive detection. It can operate purged or under vacuum and can interface to commercial cryogenic and heated sample mounts.

McPherson’s vacuum ultraviolet universal spectrophotometer features easily interchangeable five-position sample holders. Samples index while the system is under vacuum. Spectral excitation and emission wavelengths may be freely set and scanned. A high throughput monochromator with Deuterium and/or Xenon source provides tunable excitation. Emission detection is CW mode; lifetime (persistence) signal acquisition modules are available. For high sensitivity detection the system uses cooled photomultiplier and/or direct detection CCD array detectors.
