At Invisible-Light Labs, we strive to make a positive impact on the world we live in by enabling ground breaking scientific discoveries. Applications include improved disease understanding, better drugs, increased safety and more efficient protection of the environment.
Explore a world of possibilities with unprecedented sensitivity using our stand-alone room temperature nanoelectromechanical detector for IR and THz radiation .

A Rebirth of IR Spectroscopy?

To put it mildly, you are not going to get that kind of sensitivity with any classic IR technique, and this would seem to open the door to putting such sensors in all sorts of apparatus.


The IR to THz region of the electromagnetic spectrum hosts a wealth of intriguing interactions between radiation and matter, which are of particular interest for a wide range of applications.


Speed up the analysis times of biomolecules​.

Food & Agriculture

Speed up the analysis times of biomolecules​.

Environmental Monitoring

Detect and characterise low concentrations of environmental pollutants.


A completely new way of detecting IR/THz!

Nanomechanical detector technology​

We use an ultrasensitive nanomechanical thermometer to detect infrared radiation. In a recent paper we have demonstrated a sensitivity of a few femtowatt per square root hertz.

Room temperature operation

Our detector operates at room temperature and does not require any cryogenic cooling.

Broad spectral range

A broadband absorber allows the detection of mid-IR to far-IR (THz) radiation.
