15mm*15mm Square Shape Optical Grade CVD Single Crystal Diamonds
CVD Single Crystal Diamonds Description
Due to the inherent transparency of CVD Single Crystal Diamonds in
a wide wavelength range, optical characterization has long been a
common method to characterize inclusions, impurities and color
defects.
CVD Single Crystal Diamond has the widest optical transparent band
of all known solids, ranging from 0.22um to far infrared. Only the
intrinsic vibration absorption band with intensity between 2.5 and
7um interferes with the transmittance of CVD Single Crystal diamond
in the infrared region. CVD Single Crystal Diamond is transparent
in ultraviolet, visible and infrared spectra, which provides many
opportunities for lattice defects to reveal the optical activity of
electronic and vibrational transitions. Large band gap energy (5.49
EV) is a particularly favorable condition for luminescence, because
the ground state and excited state are required to be in the band
gap for radiative electron transition. The high mechanical hardness
and thermal conductivity of CVD Single Crystal Diamond greatly
support its optical applications, making CVD Single Crystal Diamond
optics very stable and wear-resistant in many aspects. When
discussing the optical properties of materials, we should carefully
consider their optical centers, because their properties and
abundance determine almost all the optical properties of materials.
In addition, the optical center content is the main parameter to
characterize the optical properties of materials. So far, more than
150 vibration centers and more than 500 electron optical centers
have been detected in CVD Single Crystal Diamond, with the spectral
range of 20-0.17um.

CVD Single Crystal Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The Lab
Grown Diamonds are produced in the laboratory, usually in a few
weeks. The chemical difference between the two is same.
So how do you distinguish between Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the Lab Grown Diamonds and
natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to discern subtle contrasts in diamond inclusions grown and
mined in the laboratory.
