Description

Mir Photonics’ Aluminum Coated Silica Fibers are engineered to excel in environments where conventional polymer-coated fibers fall short. These fibers are the ideal solution for applications requiring exceptional reliability under extreme conditions such as high temperatures and high vacuum. The aluminum coating provides efficient thermal management, ensuring long-term durability even when exposed to heat, radiation, or aggressive sterilization processes. This makes them a preferred choice for industrial, scientific, and aerospace environments where stable optical performance is critical.

These fibers maintain the inherent benefits of standard silica-silica fibers, such as excellent optical clarity, low attenuation, and chemical inertness. The addition of the metallic coating significantly enhances their mechanical strength and fatigue resistance. This enhancement offers superior protection against micro-bending, vibration, and repeated mechanical stress, ensuring the fibers can withstand demanding conditions without compromising performance.

With a broad optical transmission range from 220 to 2400 nm, Mir Photonics’ Aluminum Coated Silica Fibers are versatile enough to support a wide variety of applications. Whether utilizing UV or NIR silica fiber cores, these fibers are suitable for spectroscopy, sensing, medical, and industrial laser systems. They consistently perform across an extreme temperature range, from cryogenic conditions as low as –270°C to continuous operation at 450°C, making them a robust choice for challenging environments.
