Tittle:
Compact vacuum duct for high-sensitive materials as fibre optics for application in tunable diode laser absorption spectroscopy (TDLAS)
Summary:
A German research institute has developed a compact vacuum duct for high-sensitive materials as fibre optics for application in tunable diode laser absorption spectroscopy (TDLAS). The solution enables the positioning of optical fibres in vacuum chambers whereas rotary and longitudinal movements of the fibres are possible, hereby precise positioning and adjustment of the fibres are improved. The German research institute is searching for licensees.
Description:
Tunable diode laser absorption spectroscopy (TDLAS) is currently often limited by difficulties during the positioning of fibres in vacuum or pressure chambers. The solution offered by the German research institute is an integral solution of this problem.
The fibre which has to be inserted gets integrated in a stainless steel tube in the vacuum duct. The thick-walled, polished tube gets integrated in a special conical Teflon plug which is again positioned in a currently available industrial standard tube connection. The boundary surfaces between tube connection and plug as well as between plug and stainless steel tube are sealed during the fastening of a union nut on the rear side, elastic forming is compensated by a buffer- cavity. Due to the design, the torsion moment during the fastening proves is limited on the plug and the fibre is protected. Often existing leakages between the core and the sheath of the fibre are stopped by potting the fibre in the inner tube.
The vacuum duct is currently used in TDLAs measuring processes. The positioning and adjustment of fibres is enabled. Additionally the risk of vibration damages of instruments used in flight operations us guaranteed by the stress-free guiding of the fibre.
An increasing demand for flexible applicable solutions is expected, as existing applications areas of process control- and vacuum technology are here by increased.
Advantages and Innovations:
The offered solution leads to the following advantages:
- rotary and longitudinal movements of the fibre enable precise positioning
- no compressions
- integrated strain relief
- applicable for high-sensitive materials as glas fibre
- reusability
- leakage rate less than 5·10-10 hPa L/s
