Absorbance Spectrophotometer extends to deep ultraviolet.
Press Release Summary:
Based on direct detection, ultraviolet-sensitive CCD detectors, VUVAS Spectrophotometer features open concept sample area, and works with commercial cryostats as well as sample cells having magnesium fluoride or other UV transmitting crystalline windows. Three-position sample mount for 1 in. diameter optical samples is standard. For absorbance measurements from 120–215 nm, users can collect entire range with better than 0.5 nm spectral resolution in milliseconds.
Original Press Release:
New McPherson CCD-UV Absorbance Spectrophotometer Extends Capabilities to Deep Ultraviolet and at Faster Time Scales
Chelmsford, MA USA –
Fast DUV Spectrophotometer
McPherson’s newest VUVAS spectrophotometer capitalizes on the speed and sensitivity of direct detection, ultraviolet sensitive CCD detectors. Faster data acquisition enables more complex data sets involving spectral response vs. temperature or time. Fast acquisition also protects against potential measurement errors due to changing sample or environmental conditions. No parts move during measurement and the system attains very high reproducibility and wavelength calibration. For absorbance measurements from 120 to 215 nanometers, for example, users can collect the entire range with better than 0.5 nanometer spectral resolution in milliseconds.
Spectrophotometer Applications:
Spectral Characterization, Deep UV Optical Absorption Spectra
Absorption Spectra v. Cryogenic Temperature
Transient Absorbance / Kinetics
Material Science
Energy and Efficient Lighting Research
More about the fast spectrophotometer:
McPherson’s fast spectrophotometer features an open concept sample area. It works with commercial cryostats as well as sample cells having magnesium fluoride or other UV transmitting crystalline windows. A three-position sample mount for one-inch diameter optical samples is standard equipment. The computer optimized optical system delivers focused monochromatic light from deuterium or xenon sources to the sample. In addition to material or optical characterization, the applications include process control, measuring optical transients or kinetics. Specialty detectors with time resolution on order nanoseconds are optionally available.
Fast acquisition for a wider spectral range:
The spectrophotometer system is normally equipped with a single diffraction grating and light source. Available options include a grating turret for the monochromator and a double light-source attachment. Systems configured with these accessories operate over the range of 120 nanometers to 1 micron. Depending on the selected gratings, data acquisition occurs in 100 or 200 nanometer wide swaths. The grating can be freely set to any center wavelength as required for the application at hand.
