Remote laser Raman microscopy (ReRaM) .1. Design and testing of a confocal microprobe (Journal article)

Paipetis, A./ Vlattas, C./ Galiotis, C.

A confocal remote fibre-optic probe has been designed and tested. The theoretical design rationale for the development of the probe is presented in detail. Tailor-made optics have been introduced at both input and output positions of each fibre optic to ensure laser collimation, maximum efficiency and enhancement of Raman scattering. The probe design takes advantage of the pinhole nature of the optical fibre to apply the principles of confocal microscopy. In addition, interchangeable optics provide variable depth discrimination. The incorporation of a miniaturized video camera on the body of the microprobe allows simultaneous optical imaging during Raman spectra acquisition. The efficiency and versatility of the microprobe for a whole range of materials are demonstrated.
