كربيد السيليكون (كربيد كربيد) Round Mirror

كربيد السيليكون (كربيد كربيد) round mirrors are high-performance optical substrates fabricated via reaction bonding (RB-SiC) or chemical vapor deposition (CVD-SiC). They feature near-zero thermal expansion (1.5×10⁻⁶/°C), ultra-high thermal conductivity (200 W/m·K), and sub-nanometer surface roughness (Ra ≤ 0.5 nm). Engineered for high-power lasers, space telescopes, semiconductor lithography, and infrared optical systems, they deliver exceptional stability under extreme temperature, radiation, and mechanical load conditions, serving as a state-of-the-art alternative to metal and glass mirrors.

المزايا الأساسية

Extreme thermal stability: CTE < 2×10⁻⁶/°C (20–400°C); thermal deformation only 1/50 of glass mirrors.

Ultra-high thermal conductivity: 200 W/m·K, eliminates thermal lens effect for kW-class lasers.

Ultra-precision optical surface: Ra ≤ 0.5 nm after polishing; reflectivity > 99.5% @ 1064 nm (coated).

Lightweight & high rigidity: كثافة 3.1 جم/سم3; bending strength ≥ 400 MPa; specific stiffness (E/ρ) 4× that of fused silica.

Full environmental resistance: Radiation & acid/alkali resistant; operating temp: -200°C to 1650°C.
