We have prepared different infrared transmitting chalcogenide fibres for noncontact temperature measuring systems. Arsenic sulfide glass fibres suitable for contactless thermal sensing show a background loss below 1 dBm^-1 at a wavelength of 5 µm. Thermopile sensors (type TS-72fib), supplied with a fibre of 0.2 m length, show a maximum signal voltage of 250 μV at a black body temperature of 500 K. A fatigue test over 80 days shows no degradation of signal intensity.
