Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

All fibers were analyzed directly without additional modification or sampling accessories. The O-PTIR spectra resemble transmission-like IR spectra in non-contact (far-field) mode. Through spatially ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...
