Superior Light Management for Demanding Optics
Single-crystal CVD diamond delivers unparalleled broadband transmission – 225 nm (UV) to 25 μm (IR) with exclusion at 1.8-2.5 μm – coupled with exceptional microwave band permeability. This material’s synergy of radiation hardness, mechanical robustness, thermal conductivity (2,200 W/mK), chemical inertness, and near-zero thermal expansion defines it as the ultimate solution for advanced IR optical windows.
Mid-IR Efficiency: Refractive index ~2.4 ensures >95% transmission across 1-30 μm
Nanoscale Smoothness: Sub-50 nm surface roughness minimizes photon scattering
Precision Tolerance: Strict ±0.2 mm dimensional control
Prism Superiority: Triangular geometry maximizes mid-infrared radiation capture
