About us

Advancing the frontiers of imaging and spectroscopy for biosciences, environmental science, and advanced materials research.

Revolutionizing spectroscopy

Photothermal Spectroscopy Corp (PSC) has pioneered the breakthrough technique of O-PTIR (Optical Photothermal Infrared) 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. PSC has developed the world’s first simultaneous Infrared and Raman microscope and imaging system, mIRage-LS, providing IR and Raman data from the exact same spot, at the same time, with the same submicron spatial resolution. PSC’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.

Management team

The Photothermal Spectroscopy Corp. founding team is made up of the world’s leading scientists in the field of submicron analysis, and senior business talent with experience in the scientific equipment industry. This combination of scientific and market knowledge enables Photothermal Spectroscopy Corp. to translate its revolutionary scientific expertise into the building of a profitable high growth business.
