Description

Mir Photonics’ Aluminum Coated Silica Fibers are engineered to excel in environments where traditional 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 innovative aluminum coating not only provides superior thermal management but also ensures long-term durability, making these fibers perfect for use in harsh industrial, scientific, and aerospace settings. The robust aluminum layer effectively protects the fibers from heat, radiation, and aggressive sterilization processes, maintaining stable optical performance throughout.

While retaining the inherent advantages of standard silica-silica fibers, such as excellent optical clarity, low attenuation, and chemical inertness, the aluminum coating significantly enhances mechanical strength and fatigue resistance. This enhancement offers superior protection against micro-bending, vibration, and repeated mechanical stress, ensuring the fibers remain reliable even under demanding conditions. The aluminum-coated fibers are designed to withstand a broad optical transmission range from 220 to 2400 nm, making them versatile for various applications, including spectroscopy, sensing, medical, and industrial laser systems.

These fibers are remarkably resilient, maintaining consistent performance across an extreme temperature range from cryogenic conditions as low as –270°C to continuous operation at 450°C. This wide temperature tolerance, combined with their robust construction, makes Mir Photonics’ Aluminum Coated Silica Fibers a dependable choice for any application that demands high performance in challenging environments.
