Description
Description
Features

Hermetically sealed metal-coated optical fibers have all the benefits of silica-silica fibers. Additional significant improvements include increased mechanical strength and greater fatigue resistance compared to non-hermetic and polymer-clad fibers (PCS). Their transmittance covers a spectral range of 200 to 2400 nm, and also remains stable in corrosive chemicals that normally react with silica glass. The temperature range is from -196°C to +600°C and a humidity range is up to 100%. Hermetically metal-coated optical fibers work well in high vacuum and harsh environmental conditions.

Features:

Greatly enhanced resistance to high power laser radiation.
Higher core-to-clad ratio and enlarged NA optimised for coupling to high-energy lasers.
Better fiber cooling due to the heat-conducting metal coating.
Excellent mechanical strength and flexibility compared to polymer coated fibers.
Radiation resistant construction.
Sterilizable using ETO, steam, e-beam or gamma radiation methods.
Capability to feed the fibers into a high vacuum: the metal coating can be soldered and will not outgas
