Thorlabs is pleased to announce the release of a Surface-Enhanced Raman Spectroscopy (SERS) Substrate. Based on its proprietary textured surface technology, SERS in a non-destructive, highly sensitive ...

The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...

A point light source (laser) is used by confocal microscopy which is focused onto the sample. The reflected (fluorescence) light is often collected with the same objective and then focused into a ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...
