炭化ケイ素 (SiC) Round Mirror

主な利点

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: 密度 3.1 g/cm3; 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.
