also investigating the component durability, with very encouraging results so far.


“Initial tests have confirmed that the sensors are capable of operating for 1000 hours under high UV exposure without suffering any damage,” reports Kopta.


UV sensors as team players


The UV sensors are not only excellent “solo artists”; they are also great team players. By placing more than 100 detectors side by side in a strip, you obtain a UV camera. This device can be used to monitor plasma deposition processes, such as those employed to coat solar cells with an antireflective film.


The sensor strip can also serve as a spectrometer. In this case, the UV light is first passed through a diffraction grating which splits the light into its various spectral components, like the colours of a rainbow. Each individual sensor detects a specific wavelength and provides information on the intensity of light at that wavelength.


This would be a good way of conducting ageing tests on the mercury lamps commonly used for water disinfection or UV curing. Does the lamp still emit light of the desired intensity throughout the entire spectrum, or are certain wavelengths weaker than they ought to be?


EU funds program to speed up energy storage and solar energy production


The project will also focus on in-line high throughput manufacturing technologies for light weight construction for aerospace


LayTec is participating in the Seventh Framework Programme (FP7) funded by the European Union (cordis. europa.eu/fp7).


Together with several other companies, LayTec will work in a research project led by Germany’s largest research organisation – Fraunhofer-Gesellschaft.


The goal is the development of in-line high throughput manufacturing technologies for application in energy storage, solar energy production and light weight construction for aerospace.


LayTec will contribute to the development of process control concepts based on in-line monitoring methods allowing direct correlation of synthesis parameters with
