Lower cost laser-based IR chemical imaging microscope

Spero-LT 340

The Spero-LT 340 has been economically configured to get the most out of your research for a lower cost. With all of the same high-performance specifications in speed and resolution as the Spero-QT 340, this is a great solution for tight budgets.

DRS Daylight Solutions

A lower cost alternative to the Spero-QT 340, for laser-based IR chemical imaging

In a class of their own, the Spero® microscopes are the world’s first and only fully integrated, wide-field spectroscopic microscopy and imaging platforms based on our broadly tunable mid-infrared quantum cascade laser technology.

The Spero-LT 340 is the latest model in the Spero product family. The LT offers the same high-performance speed and resolution specifications as the Spero-QT 340 flagship model but is economically configured to address a wide range of materials and life sciences research applications while fitting within tight budget constraints. Contact us to learn what configuration options are available.
