Metal-coated Fibers

Aluminum-coated silica fibers combine the outstanding properties of silica fibers with increased mechanical strength and excellent fatigue resistance. They can withstand temperatures from –270°F to 400°F, are suitable for vacuum applications, and remain reliable even at 100% humidity. This makes them the ideal solution for demanding applications. 

Depending on the fiber core, the transmission range extends from UV (220 nm) to near infrared (2400 nm). This makes AlSilica fibers particularly suitable for high-temperature applications and environments where they are exposed to aggressive chemicals or radioactive radiation—for example, borehole measurements, high-power lasers, or medical devices.

Silica fibers coated with a copper alloy deliver maximum performance even under extreme operating conditions. They combine the proven robustness of silica-silica fibers with significantly higher mechanical strength than polymer-coated alternatives. Temperatures ranging from –270 °C to 400 °C and 100% humidity are no problem. They are also particularly resistant to material fatigue. The wide transmission range (220–2400 nm) makes these fibers very versatile. Among other things, they are ideal for high-temperature and chemical environments, nuclear technology, oil and gas drilling, high-power lasers, medicine, and soldered fiber bundles.
