Illustration of directionality and wide spectral bandwidth of a supercontinuum source. Supercontinuum light is guided from an optical fiber into a parabolic mirror, which collimates the light. Radiation beam is white and has a diameter of 2 cm. Supercontinuum light propagates few tens of centimeters and reflects from two mirrors. Light is then focused into a diffraction grating, which reflects the wavelenghts of the supercontinuum into different directions showing two rainbows.

Advanced optical spectroscopy techniques

The Applied Optics (AO) group studies and develops advanced optical spectroscopy techniques to monitor e.g. atomic and molecular concentrations. The AO group works mostly with gas phase detection, and utilizes the latest photonic components. The group is introducing new online monitoring techniques that have industrial potential.
