Spero-QT®

Spero®QT | LT
ULTRAFAST, WIDE-FIELD MID-IR MICROSCOPYThe Spero-QT® remains the highest-performance and mostversatile infrared microscopy platform available. Powered byDaylight’s award winning quantum cascade laser (QCL) technology,
the small desktop sized instrument uses a proprietary wide-field, lownoise imaging architecture to enable real-time spectroscopic analysis
for a range of Pharmaceutical, Materials and Life Sciences
applications. The Spero-QT is equipped with a high-precision
automated sample stage which accommodates as many as threestandard microscope slides. Finally, a large sample compartment area
makes the Spero-QT compatible with a variety of microfluidic devices
and accessories.
Our latest model, Spero-LT, has been economically configured to get
the most out of your research for a lower cost. With all of the samehigh-performance specifications in speed and resolution as theSpero-QT, this is a great solution for tight budgets.
INSTANTANEOUS RESULTS IN LIVE MODE
Produces hyperspectral data cubes in seconds and also supports live
discrete-frequency imaging, eliminating standard, time-consumingworkflow steps to acquire data.
