    Custom Optical Grade Borosilicate Sight Glass with High Temperature Resistance

    Custom Optical Grade Borosilicate Sight Glass with High Temperature Resistance


    1. Material Composition

    • ‌Borosilicate glass‌: High-purity material (e.g., Schott B270 or Pyrex equivalent) with low thermal expansion (3.3 × 10⁻⁶/K) and chemical inertness.
    • ‌Optical grade‌: Precision-polished surfaces with >90% light transmission and minimal wavefront distortion.

    2. Key Properties

    • ‌Temperature resistance‌: Sustains 450°C continuous use (short-term peaks to 500°C) without deformation.
    • ‌Thermal shock tolerance‌: Withstands ΔT > 150°C (e.g., rapid cooling from 300°C to room temperature).
    • ‌Mechanical durability‌: Hardness of 6.5 Mohs, pressure resistance up to 10 bar (customizable for higher demands).
    • ‌Chemical stability‌: Resists acids (except HF), alkalis, and organic solvents.


    ‌3. Core Functions

    • ‌Process monitoring‌: Real-time visualization of fluids/particles in pipelines or reactors.
    • ‌Safety barrier‌: Transparent shield for hazardous environments (e.g., high-pressure systems).
    • ‌Optical clarity‌: UV to IR compatibility (280nm–2.5μm) for spectroscopy or laser applications


    4. Applications

      • ‌Industrial‌: Chemical reactors, oil refineries, and power plant boilers for inspection windows.
      • ‌Laboratory‌: Autoclaves, vacuum chambers, and high-temperature furnaces.
      • ‌Medical/Pharma‌: Sterilizable viewports in bioreactors or pharmaceutical mixing tanks.
      • ‌Energy‌: Solar thermal systems and nuclear plant monitoring equipment.
