IR-3 workstation is a Digilabs UMA-500 Infrared Microscope is a single element detector FTIR microscope ideal for characterizing small and heterogeneous samples and is configured for the Mid-Infrared region only. This instrument is dependent on IR-2 to operate. Measurements can be made in transmission, reflection, attenuated total reflection (ATR), and grazing angle with this instrument. Methodologies that are most often conducted with this instrument are micro-sample measurements in; transmission, reflection, attenuated total reflection (ATR), grazing angle, cryogenic work and laser photolysis.


  • Spectrum measurements (transmission, absorbance, reflection) over a wavenumber range of 7,500–450 cm1 (1.3μm–22.0μm)
  • Self assembled monolayer (SAM) characterization
  • Synthesis characterization
  • Reaction monitoring
  • Materials analysis
  • Defect and surface contamination analysis
  • Laboratory instruction in spectroscopy
  • Spectroscopic research experiments
  • Micro cryogenic characterization of samples
  • Micro laser photolysis
  • Attenuated Total Reflection (ATR)
  • Diffuse Reflection (DR)
  • Grazing Angle (GR)


  • Beam Splitter
    • Extended range KBr (Mid-Infrared)
  • Detector
    • Liquid Nitrogen cooled MCT-A (Narrow band 7,500–650 cm-1)
  • Source
    • Water-cooled SiC Ceramic (Mid-Infrared)
  • Objectives
    • 4X visible light
    • 15X Cassegrain visible / infrared light
    • Grazing angle objective
  • Additional
    • Slide-on Ge ATR accessory
    • The spectrometer and sample compartment are purged with dry compressed air, which reduces the possibility of atmospheric water or CO2 contamination of the spectra and samples.
    • A wide range of sample compartment FTIR accessories are available
    • “Win IR-PRO” software for complete data collection and processing


  • Spectral Range: 7,500-450cm-1
  • Maximum Resolution: 0.1 cm-1
