Description

art photonics’ Aluminum Coated Silica Fibers are the optimal solution for applications in high temperature, vacuum and harsh environment conditions.

Al-coated fibers have all benefits of silica-silica fibers. Additional significant advantages include a superior mechanical strength and better fatigue resistance compared to polymer coated fibers.

The transmission range spans 220 to 2400 nm depending on UV or NIR silica fiber core choice. The working temperature range is from -270°C to 400°C; humidity – up to 100%.
