Optical Photothermal Infrared Spectroscopy & Microscopy
Submicron IR with simultaneous Raman spectroscopy, co-located
Fluorescence and high-speed label free IR imaging
Advancing the frontiers of IR spectroscopy
Photothermal Spectroscopy Corp. is advancing the frontiers of vibrational spectroscopy and chemical imaging with breakthrough Optical Photothermal Infrared (O-PTIR) technology. O-PTIR overcomes key limitations of traditional FTIR including poor spatial resolution, time-consuming sample preparation, and spectral artifacts,
O-PTIR uniquely delivers multimodal capabilities for spectroscopy, imaging, and microscopy, combining sub-micron IR with simultaneous co-located Raman, and Fluorescence microscopy. Our mIRage products integrate these in easy to use, high throughput benchtop instruments.
Enable new research, solve key industrial challenges
Using the mIRage product family, scientists can exploit O-PTIR for high-impact research across life science, microplastics, materials science, bio-pharma and beyond.
For industry, mIRage solves critical problems and accelerates data acquisition, including characterising organic contamination, identifying material composition, and pinpointing failure analysis.
