Copper Coated Silica Fibers

Categories: , Tags: , ,

Main features:

  • Working temperatures* up to 600°C
  • Excellent mechanical strength and flexibility
  • No outgassing under high vacuum conditions
  • Solderable into connectors (epoxy-free option)
  • Effective heat rejection along metal coating
  • Steaming, ETO, e-beam or gamma sterilizable

* Working temperatures range is valid for using in non-oxidizing atmospheres

Description

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

Cu-alloy 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 600°C; humidity – up to 100%.
