Measurement of Lateral Resolution in Confocal Raman Spectroscopy Using Indium Arsenide Nanowires

Journal of Raman Spectroscopy, EarlyView.
Lateral resolution is a key performance parameter for confocal Raman spectroscopy. We propose a protocol using an indium arsenide nanowire reference sample to quantitatively measure the resolution. The suitability of the method has been demonstrated through an international comparison with 15 participants. ABSTRACT Lateral resolution is a key figure of
