Imaging gratings for multiorder microspectrometers realized by interference lithography using supplementary holograms
The strong demand for rugged and miniaturized spectrometers is driven by applications such as in-line process control in pharmacy or in agri-food business. In this contribution we present the concept and the experimental results of a realized miniaturized optical spectrometer working in a multi-order principle. This concept allows high optical performance while simultaneously the necessary construction space shrinks drastically.
