The Vacuum Ultraviolet Analytical Spectrophotometer (VUVAS) is for wavelength dispersive spectral measurements from 120 nm to 350 nm. The VUVAS provides results as percent transmission or reflection, with precision of 0.05 percent. It works with solid samples and can be equipped with gas or liquid sample cells. Available options include cryogenic or heated sample mounts and raster-mapping attachments. It can maintain theta/2-theta geometry for specular reflectance or deviate from it to measure

... catter or dispersive events. A single detector collects reference data as well as the final transmission or reflectance measurement. The ability of the VUVAS to prove spectral and photometric precision in situ provides high-confidence results. McPherson For information 978-256-4512 www.McPhersonInc.com
