Heat Flux Sensing and Laser Power Detection

greenTEG develops, manufactures and markets thermal sensor solutions. The company was founded in 2009 as an spin-off from the Swiss Federal Institute of Technology in Zurich. greenTEG’s thermal sensors are integrated into diverse applications by customers active in markets such as laser, building technologies, medtech, automotive, processing industry and R&D.

The products are grouped in the following:

gRAY® Laser Power Detectors

Laser power monitoring is crucial in ensuring the optimal operation of your laser system. greenTEG’s laser power detectors measure in real time and provide you with accurate data. Since all gRAY® modules are based on thermal sensors, they detect radiation power independent of the laser wavelength.

gSKIN® Heat Flux Sensors

gSKIN® Heat Flux Sensors are based on the Seebeck effect and are used for different applications such as: general heat flux measurement, U-value measurement, battery calorimetry, several applications regarding phase-change materials.

Monitoring Average Power of IR Lasers
