MIRA XTR DS: The evolution of handheld Raman for fluorescence-free material identification

The illicit world is dirty. Street drugs, back-alley labs, and improvised explosives all involve chemical agents that are dangerous to first responders and the public.

We have developed the most compact and versatile answer to these threats: MIRA XTR DS handheld Raman spectrometer.

MIRA XTR DS is the most compact, rugged handheld material ID solution on the market. It can identify more than 20,000 unknown substances in the field, with the advanced ability to eXTRact the Raman signal from fluorescent samples.

The benefits of MIRA XTR DS

When fluorescence is an issue, our competitors turn to 1064 nm systems. These systems, however, use a higher laser power for sampling, which increases the potential for sample damage. In addition, the instrument battery lifetimes are shorter and the bulkier and heavier designs prohibit single-handheld operation. 1064 nm systems are also only 30% as sensitive as 785 nm.


  • permits interrogation of sensitive samples using the low power of a 785 nm laser
  • comes with higher sensitivity and resolution in a smaller footprint than 1064 nm instruments
  • features 20,000+ library entries – the largest library available on any handheld Raman system
  • is capable of both bulk Raman and trace identification of fentanyl and other illicit drugs
