O-PTIR Microscope mIRage Photothermal Spectroscopy

O-PTIR (optical Photothermal IR) spectroscopy

• A pump-probe optical spectroscopy technique (“pump” - an IR laser , “probe” - a short-wavelength visible/NIR laser)
• Sub-micron spatial resolution: Raman-like spatial resolution, with IR spectral information
• FTIR transmission-like spectra in reflection mode by measuring the response of IR absorption (no distortions, artefacts or interference fringes)
• Non-contact technique that minimizes sample preparation and preserve molecular orientation
• Spatial resolution is IR wavelength independent
