Reliable Light Guidance at Extreme Temperatures
Fibers That Withstand Extreme Heat
High-temperature environments push conventional optical fibers to their limits. Intense thermal loads, rapid temperature fluctuations or combined heat and radiation exposure can reduce transmission, impair mechanical stability or cause premature material degradation. In critical industrial processes such as plasma coating, power generation, high-temperature furnaces or metal processing, these failures can compromise both process safety and performance.
Optical fibers for high-temperature applications are engineered precisely for these extreme conditions. With aluminum coatings, hermetic carbon layers and heat-resistant jacket materials, they maintain reliable signal quality even under long-term exposure, from cryogenic –196 °C up to sustained temperatures beyond +400 °C. These fibers are ideal for industrial sensing, process monitoring and OEM systems that require stable, long-lasting performance under continuous thermal stress.
