MICROSPEC Research and Development of Miniaturised Spectrophotometers for the Food Industry - FT0406

Spectrophotometers have universal application throughout industry, but their fragile nature, size and cost currently limits their use to the laboratory. The aim of this project is to develop a truly miniaturised, fully integrated spectophotometer for colour monitoring in the food and graphics arts industries. The project will combine two technologies which have been developed independently for a period of several years, namely the LIGA process developed by Karlsruhe Research Centre for producing micro components, such as LIGA spectrophotometers with millimetre dimensions, and photoASIC detectors developed by Paul Scherrer Institute. The combination of these components will result in micro-spectrophotometric units suitable for inclusion in truly robust and miniaturised instrumentation for most process applications. A major objective is to produce these micro-spectrophotometers using replication techniques so that they can be supplied in large numbers at very low cost. The ultimate goal is to produce the components using micro-chip technology.
1 To develop a truly miniaturised and fully integrated spectrophotometer which can be replicated at very low cost using chip technology. 2 To evaluate the instrument for colour and diacetyl monitoring in the brewing industry - both in the laboratory and in a pilot plant.
