Thin Film Optical Coated Fiber - High Damage Threshold AR/HR/Filter Coating, Optimized for Fiber Lasers, WDM Telecommunications, Optical Sensing & Medical Devices
Key Features
Precision Thin Film Deposition: Our Thin Film Optical Coated Fiber features high-performance optical coatings (AR, HR, or Filter) deposited directly onto the fiber end-face, ensuring superior control over light transmission and reflection.
High Power Resilience: Engineered with a high damage threshold (>200MW/cm²), these fibers are designed to withstand the rigorous demands of high-power laser systems, significantly reducing the risk of end-face burn-in.
Advanced Surface Preparation: Utilizing proprietary precision polishing and ion-beam cleaning, we ensure a contaminant-free interface that minimizes absorption and prevents Catastrophic Optical Damage (COD).
Customizable Optical Parameters: Optimized for a wide range of wavelengths (780nm to 1550nm). Whether you need R < 0.25% for anti-reflection or high-isolation filtering, our coatings are tailored to your specific application.
Rugged & Reliable Performance: Each coated fiber undergoes strict quality inspection to ensure film adhesion and spectral accuracy, providing long-term stability in industrial and clinical environments.
Essential Applications
Our coated optical fiber products are essential components in:
Fiber Lasers: High-reflectivity (HR) coatings for high-efficiency laser cavity mirrors and feedback suppression.
Telecommunications: Advanced filter coating in optical fiber for WDM (Wavelength Division Multiplexing) and precision signal routing.
Optical Sensing: Specialized coating fiber optic tips designed for localized refractive index sensing and environmental monitoring.
Medical Devices: Biocompatible and high-precision coatings for advanced endoscopes and laser surgery tools.
