This dataset contains data supporting the results presented in the paper "Micro-lensed negative-curvature fibre probe for Raman spectroscopy". It includes the data used to plot each figure (in .txt format).

We have developed a novel miniature micro-lensed fibre probe for Raman spectroscopy. The fibre probe consists of a single negative-curvature fibre (NCF) and a spliced, cleaved, micro-lensed fibre cap. Using a single NCF, we have minimized the generated Raman background from the silica and maintained the diameter of the probe to be less than 0.5 mm. In addition, the cap provided fibre closure by blocking the sample from entering the hollow parts of the fibre, enabling the use of the probe in in-vivo applications. Moreover, the micro-lensed cap poses an improved collection efficiency (1.5 times increase) compared to a cleaved end cap. The sensing capabilities of the micro-lensed probe are demonstrated by measuring different concentrations of glucose in aqueous solutions.
