High-temperature application - Import export

heracle developes and produces specialty optical fiber with metal coating for application in harsh environments. Fiber types include Mutimode fiber with step or graded index profiles and Singlemode fiber. All fiber fiber types can be offered with either Gold or Aluminum coating. The pure fused silica step index multimode fibers (SIMM) are optimised for applications in the UV/VIS and VIS/IR wavelengths. The graded index Multimode fiber is designed to operate at 850nm and 1300nm. The Singlemode fiber is specified accoring to according ITU-T G.652. Metal coated optical fibers are typically used under extreme conditions such as: - Aircraft, missile, rocket, turbine & jet engine monitoring; - Radiation, caustic & corrosive environments - Material fatigue sensing applications - High power laser delivery systems - Ultra high vacuum applications

Our gold coated fiber is available for both wavelength ranges: from UV, VIS up to infrared wavelength ranges. The fiber offers excellent protection against chemical corrosion & mechanical stres and is capable of withstanding extreme temperatures and harsh environments. The fiber can be terminated directly onto the coating for hermetically sealed assembly. Our Gold coated fiber has very low outgassing of volatile components. We perform 100% stringend test procedures according to international standards. Typical applications are typically for extreme conditions such as: • Aircraft, missile, rocket, turbine & jet engine monitoring • Radiation, caustic & corrosive environments • Material fatigue sensing applications • High power laser delivery systems • Ultra high vacuum applications

The MTS1HIGHTEMP is a high-sensitivity, single-channel thermopile detector for precise, non-contact temperature measurement. Tanks to the housing with a soldered filter the detector is resistant to humidity, aggressive gases and other environmental influences. The high detectivity of up to 12.2*10^8 cm√Hz/W and the high sensitivity of up to 501 V/W are achieved by back gassing with krypton and the special chip design. Influences by humidity in the measuring environment are eliminated by a filter used in the transmission range from 8 to 14 µm. These properties allow the use in applications with high requirements, such as temperature monitoring of thermally indexed process parameters in the metal industry or testing of maintenance-relevant properties in the solar semiconductor industry. The detector can be used at ambient temperatures between -20 and 180 °C. An integrated thermistor for intrinsic temperature monitoring can compensate external temperature influences.
