OF6809 Infrared (IR) Quartz Fiber

Infrared (IR) Quartz Fiber Description

Infrared (IR) Quartz Fiber is a specialized optical fiber designed for efficient light transmission in the near-infrared spectrum, typically from 0.4 µm to 2.5 µm. Made from high-purity silica (SiO₂) and optionally doped for enhanced performance, this fiber offers low signal loss and superior optical performance in IR wavelengths.

With excellent thermal stability, chemical resistance, and mechanical strength, IR Quartz Fiber is widely used in spectroscopy, environmental monitoring, medical diagnostics, industrial processing, and remote sensing. Its durability and broad spectral range make it an ideal solution for demanding infrared transmission applications.

Infrared (IR) Quartz Fiber Applications

• Spectroscopy – For transmitting infrared light in NIR and MIR spectral analysis.
• Environmental Monitoring – Used in gas detection and pollutant measurement systems.
• Medical Diagnostics – Applied in IR-based sensing and laser delivery in therapeutic devices.
• Industrial Processing – For IR sensing and control in high-temperature and chemical environments.
• Remote Sensing – Suitable for infrared data collection in aerospace and defense applications.
• Laser Delivery Systems – Transmits IR laser beams for materials processing or surgery.

Infrared (IR) Quartz Fiber Packaging

Our products are packaged in customized cartons of various sizes based on the material dimensions. Small items are securely packed in PP boxes, while larger items are placed in custom wooden crates. We ensure strict adherence to packaging customization and the use of appropriate cushioning materials to provide optimal protection during transportation.

Packaging: Carton, Wooden box, Paper barrel, Iron barrel, or Customized.

Structure of Optical Fiber

Core

• Position: Located at the center of the optical fiber.
• Material: High-purity SiO₂, doped with trace amounts of GeO₂ or P₂O₅ to increase the refractive index (n₁), enabling light signal transmission.

Cladding

• Position: Surrounds the core.
• Material: High-purity SiO₂, with trace dopants such as B₂O₃ used to slightly lower the refractive index (n₂) so that it is slightly less than that of the core. This ensures that the light signal remains confined within the core for transmission.

Coating Layer

• Position: The outermost layer of the optical fiber.
• Structure and Material: Includes a primary coating, a buffer layer, and a secondary coating.

a) The primary coating is typically made of acrylate, silicone, or silicone rubber.

b) The buffer layer generally consists of a high-performance filling gel (for water resistance).

c) The secondary coating is usually composed of high polymers such as polypropylene or nylon.

• Function: To protect the optical fiber from moisture and mechanical abrasion, while also enhancing its mechanical strength and flexibility. This extends the service life of the fiber.
