Core Advantages Of Silicon Carbide Mirror
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).
خفيف الوزن & 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.
