ABSTRACT:
An illuminator apparatus has a light source and a liquid-core light guide comprising a tubular flexible sheath of a fluorocarbon polymer material which is filled with a lightguiding fluid such as glycol, a salt solution containing a chloride, fluoride or phosophate, phenylmethyl silicone oil (n.apprxeq.1.57), PCTFE oil, polychlorotrifluoroethylene oil (n=approx. 1.40) or also pure water. The tubular sheath is internally coated with a thin film of Teflon AF.RTM., the refractive index of which is lower than that of the sheath material.
