Photothermal Spectroscopy Corp (PSC) is a Santa Barbara, CA, based scientific equipment company that pioneered sub-micron IR microscopy and spectroscopy. PSC’s vision is to enable the power of sub-micron IR spectroscopy to be applied to high value problems in both industry and academia via the adoption of O-PTIR and co-located multi-modal techniques. With the introduction of the mIRage® product, we pioneered a breakthrough sub-micron-Infrared spectroscopy and microscopy technique called Optical Photothermal Infrared (O-PTIR). O-PTIR eliminates key limitations of traditional IR spectroscopy providing sub-micron IR spatial resolution with transmission-like FTIR quality spectra in non-contact reflection mode with no Mie scattering effects. The subsequent release of the mIRage-R product combined O-PTIR with Raman introducing the world’s first simultaneous Infrared and Raman microscope and spectroscopy system, providing simultaneous IR and Raman data from the exact same spot, at the same time, with the same sub-micron spatial resolution enabling complementary and confirmatory data from both techniques. The launch of the mIRage-LS extended platform capabilities by combining O-PTIR with co-located fluorescence microscopy and further improved IR spatial resolution to sub-500nm. The mIRage-LS allows O-PTIR technology to address high value life science research problems not able to be addressed by conventional IR microscopy. O-PTIR is one of the highest growth techniques in microscopy addressing areas in life science, microplastics, bioplastics, semiconductor, Failure analysis and chemical and polymeric materials.
