US Patent No: 8869602

High frequency deflection measurement of IR absorption

---

Abstract

---

An AFM based technique has been demonstrated for performing highly localized IR spectroscopy on a sample surface by using the AFM probe to detect wavelength dependent IR radiation interaction, typically absorption with the sample in the region of the tip. The tip may be configured to produce electric field enhancement when illuminated by a radiation source. This enhancement allows for significantly reduced illumination power levels resulting in improved spatial resolution by confining the sample-radiation interaction to the region of field enhancement which is highly localized to the tip.
