Introducing the mIRage® IR Microscope - Photothermal Spectroscopy Corp

A fast and easy to use non-contact optical technique

mIRage overcomes the IR diffraction limit with an innovative technique, Optical Photothermal Infrared (O-PTIR) spectroscopy.

A tunable pulsed mid-IR laser induces photothermal effects into a sample surface, which are measured using a visible probe laser focused on the sample. The measurements are collected in a fast, easy to use manner without the need for contact-based techniques like ATR spectroscopy.

Eliminates need for thin sections

Transmission FTIR quality spectra in reflection mode

mIRage provides IR spectroscopy and chemical imaging, independent of IR wavelength. Using O-PTIR, highly sensitive IR measurements are enabled, providing transmission quality absorption without surface contact. This eliminates the need for thin samples and improves turnaround times.
