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.
