O-PTIR non-contact submicron visible probe infrared spectroscopy
The use of O-PTIR submicron visible probe with no contact to detect the photothermal IR effect is the key breakthrough. It enables non-contact, submicron IR spectroscopy in reflection mode. This provides new analytical capabilities to analyze polymers, life science samples, particulates and more.
non-contact submicron visible probe infrared spectroscopy
O-PTIR submicron visible probe non-contact detection of the photothermal IR effect overcomes the key limitation of traditional FTIR/QCL microscopy. It does this by removing the fundamental spatial resolution limits of IR spectroscopy (10-20 microns). This limit is now governed by the visible beam wavelength. O-PTIR achieves submicron spatial resolution, all in non-contact, reflection mode operation.

Spectra on thick samples that correlate to transmission FTIR
Provides the best of both worlds by combining the convenience of O-PTIR submicron visible probe in non-contact reflection mode technique with “FTIR transmission-like” quality. The spectra are collected in reflection mode, where thickness, surface roughness or particle shape/size are not issues.
mIRage combines O-PTIR and Raman
to improve results
The world’s first simultaneous IR+Raman microscopy system is a unique dual modality platform that combines all the advantages of O-PTIR with complementary Raman microscopy via simultaneous detection of the visible probe laser.
