This instrument scans in the near-, mid-, and far-infrared regions with resolution down to 0.09 cm -1 and scanning speeds up to 65 scans per second. Detectors employed are a liquid nitrogen-cooled MCT (mercury-cadmium-telluride) detector for the near- and mid-IR regions and a polyethylene film detector for the far-IR region. Included are three beamsplitters: quartz (near), KBr (mid), and solid substrate (far).
The department also has the following sampling accessories: traditional disk and solution cell holders, diffuse reflectance, specular reflectance (fixed 30 deg and a VeeMax II accessory for variable 30-80 degree incidence), and horizontal attenuated total reflectance (HATR). Classes and research groups utilize this instrument for characterization of organic and inorganic chemical reaction products as well as thin solar cell material films.
Instrument features include spectral substraction, mathematical correction, baseline correction, and a library of thousands of reference IR spectra.
