Introducing our high-performance glass fibers designed for infrared (IR) applications, crafted with pure fused silica glass. These fibers boast a low OH content and maintain a uniform refractive index across their entire diameter, making them ideal for use in the wavelength range of 400 nm to 2400 nm, covering both visible (VIS) and infrared (IR) spectrums. The versatility of these fibers is enhanced by their coatings, which are available in materials such as acrylate, silicone, or polyimide, ensuring protection and durability in various environments.

Multi-Coating Optical Fiber Platform for Flexible System Integration
FiberTech Ultrasol step-index multimode VIS-IR fibers are designed as a modular optical transmission platform offering multiple coating and jacket configurations to support a wide range of environmental, mechanical, and thermal requirements. Options including single acrylate, dual acrylate, silicone-coated, and polyimide-coated fibers enable system designers to select optimized performance characteristics for applications ranging from laboratory instrumentation to harsh industrial environments. This flexible architecture allows a single fiber platform to serve diverse photonics, sensing, spectroscopy, and laser delivery applications while maintaining consistent optical transmission performance across VIS-IR wavelength ranges.

Choosing the Right Fiber Coating for Your Application
Different coating materials provide distinct mechanical, thermal, and environmental performance characteristics. Single acrylate coatings are widely used in standard laboratory and industrial environments, while dual acrylate coatings offer enhanced mechanical durability. Silicone coatings extend operational flexibility into higher temperature ranges, and polyimide coatings enable fiber operation in extreme thermal and harsh-environment conditions. This modular approach allows optimization of fiber performance across a wide range of photonics and industrial applications.
