Metal Coated Silica Fibers
Metal Coated Silica Fibers
SILICA step index high OH solarization resistant fiber(190-1200nm)
Special fibers support applications in high-temperature and high-vacuum areas and also withstand aggressive substances.
These fibers are provided with a hermetically sealed metal coating and are thus protected against the penetration of liquids and gases. They are suitable for operating temperatures between -196°C and +400°C, do not outgas even under high vacuum conditions, and resist both organic solvents and other aggressive substances. The fibers are significantly more mechanically resilient than fibers with organic coatings such as hermetic carbon coatings.
More specifically, aluminum coating does not accumulate static electricity and simplifies fiber cooling through good thermal conduction Aluminum and Copper are available and can in principle be realized for all our special glass fibers. Soldering of the fibers is also possible in principle.
