The main advantage of using infrared fibres in a number of applications is the delivery of radiation to a remote point
of application. Fluorozirconate (O.3-5tm) and chalcogenide glass fibres (2-12gm) are receiving most attention,
particularly in remote spectroscopy, laser power delivery, fibre lasers and thermal imaging.
