    Product Description


    Sapphire Tubes Customized Tubular Components 99.999% Al₂O₃ 80%-90% Transmittance For Endoscopic Catheter


    Sapphire tubes and customized tubular components are high-performance optical elements precision-engineered from single-crystal aluminum oxide (α-Al₂O₃). Distinct from standard circular tubing, these custom sapphire tubes can be fabricated with specialized cross-sections (square, hexagonal, D-shaped, etc.) while maintaining sapphire's intrinsic properties: ultra-high hardness (Mohs 9), broad-spectrum transmission (UV to IR wavelengths), and exceptional chemical stability. Their unique structural adaptability makes them ideal for specialized optical transmission, extreme-environment sealing, and fluid control systems, with critical applications in high-power lasers, semiconductor equipment, and high-temperature observation systems.




    Key Characteristics


    1. Complex Structural Customization:


    · Supports asymmetric cross-sections (internal/external polygons, tapered diameters, etc.) with inner diameter tolerances controlled within ±0.05mm, meeting requirements for complex optical paths or fluid channels.


    2. Extreme Environmental Resistance:


    · Withstands prolonged 800°C operation (short-term 1500°C exposure), exhibits excellent thermal shock resistance (CTE: 5.3×10⁻⁶/°C), and resists strong acid/alkali corrosion (pH1-14), making it suitable for chemical reactors or plasma processing equipment.


    3. Optical & Mechanical Performance:


    · 80% transmittance from UV to mid-IR, with optional anti-reflection coatings (<1% reflectivity) on inner/outer walls

    · Flexural strength >500MPa, maintaining structural integrity even at minimal wall thicknesses (0.5mm)


    4. Sealing & Surface Properties:


    · Internal/external surfaces polished to Ra≤10nm, capable of high-vacuum sealing (leak rate <1×10⁻⁹ Pa·m³/s), meeting cleanliness standards for semiconductor and laser systems.

    2. Semiconductor Processing Equipment:
    Serve as observation ports or gas delivery tubes in etchers and MOCVD reaction chambers, resisting plasma erosion while maintaining contamination-free transmission.


    3. High-Temperature Industrial Monitoring:
    Function as viewport tubes in molten metal or glass furnaces (>1000°C), ensuring stable signal transmission under extreme conditions.


    4. Medical & Scientific Instruments:
    As endoscopic catheters or X-ray guide tubes in synchrotron radiation systems, combining biocompatibility with radiation stability.



    FAQ


    1. Q: What are the advantages of sapphire tubes compared to quartz tubes?
    A: Sapphire tubes offer 3x higher hardness (Mohs 9), 2x better thermal conductivity (35W/m·K), and superior chemical resistance, especially in extreme pH environments.


    2. Q: Can sapphire tubes be customized for medical endoscope applications?
    A: Yes, we provide medical-grade sapphire tubes with <10nm surface roughness (Ra), biocompatible certification (ISO 10993-5), and precision inner diameters down to 0.3mm.
