CHELMSFORD, Mass. — McPherson Inc.’s new UV absorbance spectrophotometer, VUVAS, is suitable for materials and optical characterization, process control and kinetics and optical transient measurement.
The instrument uses direct-detection UV-sensitive CCDs to acquire complex data sets involving spectral response versus temperature or time. Featuring an open-concept sample area, VUVAS works with commercial cryostats as well as sample cells with magnesium fluoride or other UV-transmitting crystalline windows. The computer-optimized optical system delivers focused monochromatic light from deuterium or xenon sources to the sample.
VUVAS comes with a single diffraction grating and light source. A three-position mount for 1-in.-diameter samples is standard, and no parts move during measurement. Options include a grating turret for the monochromator and a double light source attachment.
