Diamond Temperature Measurements
Trrough Methane Plasma
Diamond optical properties
Up to 2.5mkm there is no any real absorption for diamond structure
Methane Plasma spectral emission
The structure of thermal emission from growing diamond layer and from substrate with the same temperature
Diamond emissivity structure
Silicone substrate transmittance (including surface reflection)
Examples of possible solutions
Result of test running with H2 atmosphere, with substrate and without diamond. (photo of PC screen with AST Application SW– Chart view)
