Delivering reliable operation in extreme conditions, Fiberguide Industries provides its metal jacket series of gold and aluminium coated optical fibres. These fibres have proven effective in a number of scientific applications including Raman spectroscopy for high temperature analytical measurements.

Originally developed for ultra high reliability telecommunications, the metal coating preserves the fibres mechanical strength and provides resistance against static fatigue caused by long term tensile loading. Gold and aluminium coated fibres also can withstand a wide range of temperatures, with aluminium coated fibres rated from -269C to +400C and gold rated from -269C to 700C.

Gold or aluminium coating can be applied on continuous lengths to a wide variety of multimode, step index, graded index and single mode fibres. Core to clad ratios of 1.1, 1.2 and 1.4 are available with numerical apertures of 0.12 and 0.26. Non-standard sizes can also be manufactured by request.
