Metal-coated Silica Fibers: Multi-Mode, Cu-alloy Coated

Name: Metal-coated Silica Fibers: Multi-Mode, Cu-alloy Coated
Brand: Art photonics GmbH
Availability: InStock

Description

art photonics' Copper-alloy Coated Silica Fibers are engineered to deliver exceptional optical performance under extreme environmental conditions, making them an ideal choice for demanding industrial, medical, and scientific applications. These fibers combine the optical clarity and wide transmission range of silica fibers (220–2400 nm) with a mechanically robust copper-alloy coating that enhances thermal tolerance and resistance to fatigue.

Designed for use in high temperatures up to +600°C and cryogenic environments as low as –270°C, these fibers are also optimized for high humidity (up to 100%) and vacuum applications, offering zero outgassing performance. The durable metallic coating allows soldering without the need for epoxies, ensuring compatibility with high-vacuum systems and applications requiring sterilization, such as ETO, gamma, or e-beam processes.

Available in single-mode, graded-index, and step-index multimode configurations, these fibers offer flexible options for custom integration, from downhole sensing in the oil and gas industry to high-power laser delivery and medical diagnostics. With superior mechanical strength, high static fatigue resistance, and customizable numerical apertures, these fibers offer unmatched durability and precision in the harshest environments.
