The detection of beads with a diameter of 200 nm, which is smaller than the diffraction limit, was realized, demonstrating the exceptional sensitivity of the line-scan Raman spectroscopy system.

Extended InGaAs arrays can also be used, which can detect out to 2.6 µm or 2.2 µm, but these detectors are not only more expensive, but also noisier than conventional InGaAs detectors. It is slightly ...
