The new MIRcat-QT adds high-speed tuning, higher spectral repeatability, improved thermal management, and longer-wavelength options to the field-proven MIRcat laser system. A true one-box, fully automated system, MIRcat-QT�s flexible, modular design allows users to factory-configure their system for up to four pulsed or CWpulsed modules, upgrade it later, or add a visible aiming beam. Application: Photo-acoustic spectroscopy (PAS), Hyperspectral imaging, Combustion diagnostics, Bio-medical imaging & diagnostics research, Atmospheric remote sensing, Nanoscale imaging, Breath analysis, Standoff detection research (e.g. explosives, toxic industrial chemicals), Materials characterization, Infrared countermeasures (IRCM) research, Illumination
