CVDダイヤモンド基板

Enjoy the benefits of diamond's unique properties – very broad transmission range, extraordinary hardness, high thermal conductivity, high resistance to thermal shock and thermal lensing, and unique electronic properties.

Coherent employs chemical vapor deposition (CVD) to grow single crystal and polycrystalline diamond in high volume, consistently producing material with low scatter, minimal absorption, and low birefringence in a wide range of cross-sectional sizes and thicknesses. Application include optics, thermal management, electronics, and quantum sensors.

CVDダイヤモンドの特性

Coherent supplies CVD diamond material in sizes up to 145 mm diameter and 2 mm thickness, and can achieve a thermal conductivity of over 2200 W/m-K.
