from proteins to stars

Explore a world of possibilities with unprecedented sensitivity using our stand-alone room temperature infrared and terahertz detectors.

Invisible-Light Labs enables you to achieve new paradigms by allowing you to hear the invisible infrared radiation with our ultra sensitive nanomechanical resonators. Applications include improved disease understanding, better drugs, increased safety and more efficient protection of the environment.


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. The ability to obtain IR/THz molecular fingerprints with high sensitivity at room temperature is of particular interest for a wide range of applications such as pharmaceuticals, fundamental research, food & agriculture, environmental monitoring, security and materials.


Speed up the analysis times of biomolecules​, monitor processes online, quality control, counterfeits, polymorphism,..

Food & Agriculture

Speed up the analysis times of biomolecules​, assess food spoilage and contamination, monitor pasteurisation,...

Environmental Monitoring

Detect and characterise low concentrations of environmental pollutants.


Hear the light: A completely new way of detecting IR/THz!

Nanomechanical detector technology​

We use an ultrasensitive nanomechanical thermometer to detect infrared and terahertz radiation. Click here to read our PNAS paper where we demonstrated a sensitivity of a few femtowatt per square root hertz. Click here to read about how our new technology expands the IR/THz spectroscopy toolkit and even allows the drumming up of single-molecule beats!

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 with high sensitivity.
