Abstract
System for performing chemical spectroscopy on samples from the scale of nanometers to millimeters or more with a multifunctional platform combining analytical and imaging techniques including dual beam photo-thermal spectroscopy with confocal microscopy, Raman spectroscopy, fluorescence detection, various vacuum analytical techniques and/or mass spectrometry. In embodiments described herein, the light beams of a dual-beam system are used for heating and sensing.
Claims30
A method for analyzing a sample, the method comprising:
- a. illuminating a region of the sample with a light beam of infrared radiation;
- b. illuminating at least a sub-region of the region of the sample with a probe light beam having a shorter wavelength than the light beam of infrared radiation;
- c. analyzing probe light collected from the sample to obtain measurements indicative of infrared absorption of the sub-region of the sample;
- and
- d. analyzing probe light collected from the sample to obtain measurements indicative of Raman scattering of the sub-region of the sample.
