For some applications a very specific fibre or probe is needed. Avantes has over 25 years of experience in designing the custom probes for unique applications. Avantes has significant expertise in designing fibre optics for high-temperature (HTX), high-pressure (HP), vacuum, and other difficult conditions. Avantes wide variety of standard and custom materials can be configured to provide a fibre assembly which can meet the challenges of your environment. Below are some examples of our special designs. Please contact us to discuss your needs. High-temperature UV/VIS/NIR probe with gas connection The universities of Bochum in Germany and Utrecht in the Netherlands contacted us with a problem conducting high-temperature measurements at low pressure of dehydrogenation of propane: ideal conditions for the creation of cokes. Therefore every time the probe was contaminated with coke residue on the tip, meaning they could only do a single test, after which they had to replace the probe. Avantes responded by designing this high-temperature probe. It’s resistant to temperatures of 700 degrees centigrade or more and features a connection for gas insertion into the probe. So far, during one test the probe was used over 150 hours continuously, with temperatures of 550-600 degrees. The gas used was nitrogen. The result was a clean tip, a re-usable probe, and very happy customers.
