Mir Photonics LLC is proud to present its Copper-alloy Coated Silica Fibers, a breakthrough in fiber technology designed for the most challenging environments. These fibers are engineered to excel where traditional fiber solutions fall short, offering exceptional performance in extreme conditions such as high temperatures, high vacuum, and harsh operational settings. With a focus on industrial, scientific, and aerospace applications, these fibers provide unparalleled optical stability combined with robust thermal and mechanical resilience.

What sets these copper-alloy coated fibers apart is their ability to maintain the inherent benefits of traditional silica-silica fibers while significantly enhancing mechanical strength and durability. The metallic coating not only boosts resistance to fatigue and mechanical stress but also ensures superior performance compared to polymer-coated fibers. This makes them an ideal choice for demanding applications where reliability and longevity are critical.

The optical transmission capabilities of these fibers are impressive, covering a broad spectrum from 220 to 2400 nm. This wide range is achieved through the selection of UV or NIR silica fiber cores, allowing for versatile use across various optical and spectroscopic applications. Remarkably, these fibers maintain consistent performance across an extreme temperature range, from cryogenic levels as low as –270°C to continuous operation at temperatures up to 600°C. Additionally, they can withstand humidity levels of up to 100% without compromising their optical or mechanical integrity, ensuring reliable operation in diverse environmental conditions.
