VisIR Spectrophotometer
|
|
McPherson, Inc. Vis IR Spectrophotometers can be equipped in a variety of ways. We have routine reflectometers and special versions for vacuum reflectometry. We can equip these systems with any monochromator from our line so you can specify the wavelength resolution and bandpass you need.
Vis IR Reflectance and Transmittance Spectrophotometer features continuously adjustable sample and detector angles. The reflectometer is easy to use and the new, stabilized single beam spectrophotometer provides improved measurement precision. The double monochromator consists of a prism predisperser combined with the monochromator. This assures low levels of stray light, provides uncontaminated spectra, and eliminates filters. SNAP IN gratings and thermoelectrically cooled detectors permit operation from 190 to 350-nm with Deuterium and 350 to 2500-nm with tungsten sources. Bilaterally adjustable slits allow the user to adjust bandpass for the measurements requirement.
The Vis IR Spectrophotometer is complete with integrated software controls of all acquisition functions. Data is displayed during scans and extensive post processing arithmetic, display and plotting capabilities are included.
Direct angular readout of sample and detector positions. Position locks for optimum repeatbaility in routine applicaitons (eg. witness samples.)
