IR Spectroscopy at Stony Brook

[If you had graphics, you would see our IR spectrometer]

Mike Martin recording IR spectra on our BOMEM MB-155 mid- and near-infrared FTIR spectrometer. Since the spectrometer is barely visible on this picture, we took another one, below.
[another spectrometer view]

Our new custom sample space (in clear plexiglass) is visible in this photograph. A specialized IR microscope is visible in the back left of the photo in which we can obtain the spectra of very small samples. We can measure samples in a temperature range from 4.2K to 900K.We study alkali metal doped C60 and high temperature superconductors.
[IR sample would be here]

Here is a sample made by Laszlo Forro for the measurement of the IR transmission of thin single crystals of Bi2Sr2CaCu2O8. The photo was taken under a microscope by Dan Koller.

The lighter hole on the right hand side is for the reference beam; the transparent sample covers the hole on the left side. Four thin gold leads are attached to the sample for DC resistivity measurement. The thick leads are connected to a heater below the sample. The diameter of the holes is 400 microns. You need real steady hands to do this!!
