Infrared Spectroscopy Laboratory
Planetary Science Directorate
Southwest Research Institute

Welcome to the Infrared Spectroscopy Lab. This laboratory supports studies of the vibrational, or thermal infrared, properties of rocks (including meteorites) and minerals, using both emission and reflection measurement techniques. Our primary users are interested in understanding the variation in spectral characteristics of samples of differing mineralogies, chemistries, structures, particle sizes, shock levels, etc. The knowledge that is gained from these studies is applied to the analysis of infrared spectra of unknown samples, as well as remote sensing data collected over Earth and Mars.

The lab is equipped with a Nicolet 470 FTIR spectrometer with a CsI beamsplitter for coverage to 200 cm-1. The spectrometer is configured for both hemispherical reflectance and emission measurements. Hemispherical reflectance measurements (2.5 - 14 microns) are acquired via a Labsphere integrating sphere and cooled MCT-A detector. The emission configuration is modeled after the configuration at the Thermal Emission Spectrometer (TES) laboratory at Arizona State University. We welcome opportunities to collaborate on projects with investigators from other institutions.

Watch this page for updates and information about the status of our lab.


February 2010

In an ongoing effort to augment the capabilities of our lab, we have just purchased a new MCT-B detector for the hemispherical reflectance set up. We expect to have the new detector installed and checked out by the end of March. This detector will enable us to measure out to 25 microns, which is particularly important to measuring oxides and oxide-bearing materials.

March 2008

The spectrometer was installed last fall, and is up and running. Currently, we are in the planning stages of developing a sample chamber that will permit us to make measurements in vacuum, to better simulate conditions on airless bodies.

31 July 2008

The spectroscopy lab buildout is complete, and the equipment has been delivered. Installation and checkout will occur throughout the month of August.

Read about the laboratory setup in our 2005 Lunar and Planetary Science Conference abstract. In other news, we have designed a sample stage for the emission side that will allow us to make fine adjustments to sample position in the x and y directions in addition to selecting the spot size via height adjustments. This stage will permit analysis of much smaller samples than previously has been possible.
