MID INFRARED SPECTROMICROSCOPY (MID-IR)

AGILENT

Agilent Cary 670 FTIR Interferometer with Cary 620 Microscope

  Maintenance & Development

The Agilent Cary 670 spectrometer with a Cary 620 Microscope is a state of the art instrument for infrared spectromicroscopy and Chemical Infrared Imaging. The Cary FTIR system is equipped with a 128 x 128 pixel Focal Plane Array detector and provides high spatial resolution, large field of view, high sensitivity and fast collection times.

The system is ideal for imaging biomedical and biological materials, agricultural samples, materials such as polymers, art specimens, and other samples suited to infrared chemical analysis.

The advantages of the Agilent chemical imaging system include:

  • large field of view (up to 700 µm x 700 µm in a single measurement)
  • rapid acquisition times
  • calibrated mosaic stitching for large-area measurements

This spectrometer is an excellent complement to high-brightness synchrotron radiation FT-IR spectromicroscopy where rapid collection of large areas will help identify areas of interest for closer study.
