The Nicolet 6700 is a state of the art Fourier Transform IR/Visible spectrometer.  It was installed in July 2008.  It is equipped to analyze samples from 200 um to approximately 380  nm.  It has the following equipment:

Beamsplitters

• Substrate for Far IR
• Extended Range KBr for Mid IR
• Quartz for the Near IR and Visible Regions

Sources

• Everglo source
• White Light Source

Detectors

• Polyethylene for Far IR
• DTGS room temperature for Mid IR
• InGaAs detector for Near IR
• Quartz detector for Near IR and Visible
• MCT/A Liquid Nitrogen cooled detector for high sensitivity in the Mid IR

The instrument is equipped with several modules to allow for analysis of several kinds of samples

• Single Bounce ATR Module - ZnSe Crystal
• Multi Bounce ATR Module - flat and trough plates - ZnSe crystals
• DRIFTS Module
• Vertical ATR with ZnSe and KRS-5 crystals
• Grazing Angle Specular Reflectance module
• Variable Angle Specular Reflectance module

The software used on the instrument is the versatile OMNIC Version 8.0, equipped with the ValPro Validation package for monthly calibrations
