<p>Method and apparatus for identifying CVD diamond comprises (i) placing a clean diamond on a fixed platform; (ii) illuminating the diamond with light having various wavelengths; (iii) receiving reflected light from the diamond; (iv) calculating a reflectance value at each wavelength based on a light intensity at each wavelength of the reflected light, generating a spectral reflectance curve; (v) determining whether the spectral reflectance curve has a sharp trough, then storing the diamond if the spectral reflectance curve thereof does not have the sharp trough, while selecting the diamond for a further identification if the spectral reflectance curve thereof has the sharp trough; and (vi) determining whether the sharp trough of the diamond selected from the step (v) is at a wavelength between 227 nm and 233 nm, and identifying the diamond to be the CVD diamond if the sharp trough is at the wavelength between 227 nm and 233 nm.</p> |
