CVD Diamond Wafer Description

CVD Diamond Wafer has outstanding physical and chemical properties. It has an almost continuous band of optical transparency from UV to THz. Diamond is one type of carbon and has the highest hardness and thermal conductivity at the same time with high wear resistance, chemical inertness, and excellent radiation resistance. CVD Diamond Wafer can be used in multiple band ranges such as X-ray, ultraviolet, infrared, microwave, and so on.

It plays an important role in high energy input, low dielectric loss, high Raman gain, low beam distortion, erosion resistance, and other aspects that can’t be replaced by general optic materials. CVD Diamond Wafers are the best thermal management material for high heat flux devices due to their excellent thermal conductivity.
