A VTT led research project is developing compact spectral imaging and gas measurement technologies for industries and medical diagnostics. Innovations based on the science of light, i.e. photonics, use, for instance, infrared light to identify gases. With the new optical MEMS solutions, instruments and sensors are easier and cheaper to manufacture from readily available and non-toxic raw materials.

The EPheS (Efficient Photonics for Sustainable Imaging and Sensing) project, involving four pioneering companies and two research institutes, is developing tunable optical sp…
