Reliable Light Guidance at Extreme Temperatures
High-temperature environments push conventional optical fibers to their limits. Thermal stress, temperature cycling, and harsh environments place high demands on material performance and mechanical durability. In plasma processes, power plants, industrial furnaces, or metal processing, solutions are therefore required that deliver reliable performance over extended operating periods.
Optical fibers from Ceramoptec 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.
Typical Applications
- Plasma processes & coatings: reliable light transmission under extreme temperatures and radiation exposure
- Power plants & energy facilities: precise signal delivery for process and safety monitoring
- Industrial furnaces & combustion processes: stable fibers for the reliable monitoring of melting and burning operations
- Aerospace: high-performance fiber optic systems for propulsion and structural monitoring
Selection Criteria for Fibers
In high-temperature applications, fiber selection is primarily defined by temperature range, thermal cycling, and environmental conditions. Precise matching of the fiber to these factors supports stable signal transmission and reliable system performance over extended operating periods.
Key selection parameters:
- Temperature range: continuous and peak operating temperatures
- Thermal cycling: impact of heating and cooling processes
- Material stability: behavior of glass, coatings, and protective materials
- Mechanical load: relevant for vibration or dynamic applications
- Environmental conditions: chemical exposure, protective atmospheres, humidity
