Optical-Grade CVD Single Crystal Diamond: Unmatched Spectral Performance
CVD-grown single crystal diamond delivers the broadest light transmission range among solid materials, spanning 225 nm (UV) to 25 μm (IR) - excluding the 1.8-2.5 μm band - with exceptional microwave transparency. Its unique combination of radiation resistance, extreme hardness, thermal conductivity, chemical inertness, and minimal thermal expansion makes it the premier choice for advanced infrared optical systems.
Critical Specifications
- Mid-IR Optimization: Refractive index ~2.4 ensures high-efficiency transmission across 1 -30 μm wavelengths
- Surface Precision: <50 nm roughness for minimal light scattering above 1 μm
- Dimensional Accuracy: ±0.2 mm tolerance
- Triangular Prism Design: Optimized for mid-infrared radiation measurement instrumentation
Advanced Applications
- Laser Systems: High-power CO₂ lasers, disc lasers, Raman lasers
- IR Imaging & Sensing: Long-wave infrared detectors (8-14 μm)
- Spectroscopic Analysis: Precision wavelength measurement tools
- RF Technology: Gyrotron and high-power RF generator components
- Compact Optics: Miniaturized diamond lenses for lightweight designs
Competitive Advantages
The material's ultra-low optical scatter and chemical stability enable:
