Abstract: SiC Optical Lens
SiC optical lenses are precision-engineered components made from
advanced silicon carbide (SiC) material, designed to deliver
exceptional performance in harsh and demanding environments.
Compared to traditional optical materials like quartz or calcium
fluoride, SiC exhibits superior hardness, thermal stability, and
corrosion resistance, making it ideal for high-power laser systems,
semiconductor manufacturing, aerospace applications, and scientific
research.
Core Advantages:
- High-Temperature Resistance: Operates stably at temperatures exceeding 300°C without thermal
distortion.
- Exceptional Hardness: Mohs hardness of 9.2-9.3 (second only to diamond), providing
outstanding scratch resistance.
- Low Thermal Expansion: Coefficient of thermal expansion as low as 1-3×10⁻⁶/K, ensuring
dimensional stability under rapid temperature changes.
- Broad Spectral Transmission: High transmittance from ultraviolet (200nm) to mid-infrared
(10μm).
