Photothermal Spectroscopy Corp.
Photothermal Spectroscopy Corp (PSC) has pioneered the breakthrough technique of optical Photothermal Infrared (O-PTIR) technology that eliminates key limitations of traditional IR Spectroscopy providing submicron spatial resolution for IR and transmission-like FTIR quality spectra in non-contact reflection mode. More recently, PSC has developed the worldâ€™s first simultaneous Infrared and Raman microscope and imaging system, providing IR and Raman data from the exact same spot, at the same time, with the same submicron spatial resolution. PSCâ€™s vision is to enable the power of IR spectroscopy to be applied to high value problems in industry and academia via the adoption of O-PTIR.
FTIR and Raman infrared spectroscopy for material analysis are well established, mature technologies that have their practical and theoretical limitations. Now, with the breakthrough technique of O-PTIR, those limitations are shattered. The novel use of a dual purpose visible light probe not only provides for submicron IR spatial resolution, but it also doubles as the Raman excitation laser, thus providing submicron simultaneous IR+Raman spectroscopy on a single platform – the mIRage+R microscope. This generates complementary and confirmatory analysis through IR and Raman spectroscopy for a more detailed and thorough characterization for the ultimate in vibrational spectroscopic synergy.O-PTIR microscopy overcomes several of the key limitations of traditional FTIR microscopy such as poor spatial resolution and complex sample preparation. By working in reflection mode, it generates high quality spectra without any dispersive scatter artifacts that are comparable to FTIR transmission/ATR spectra.
While at the same time, O-PTIR is not affected at all by fluorescence interference, a key limitation of Raman spectroscopy, thus allowing for submicron molecular characterization that is completely fluorescence free.
