Infrared lasers for spectroscopy

Quantum cascade lasers (QCLs) combine a broad spectral tuning range of more than hundreds of wavenumbers with high spectral brightness. The infrared application laboratory at Fraunhofer IAF aims to bridge the gap between laser source and measurement system development at Fraunhofer IAF and customers.

Millimeter-wave radar system for harsh environments

Due to the harsh environmental conditions in production and manufacturing sensors have to be extremely resistant to thermal radiation, dust, smoke, and steam. Fraunhofer IAF has developed a high-performance millimeter-wave radar system for harsh environments operating at W-band (75 – 110 GHz).
