Since lab-grown diamonds have the purest chemical structure and highest thermal conductivity, their application for optical purposes can improve the quality of laser beams. Lenses, windows and prisms made of diamond plates have a high demand in medical and military industries. They are also valuable components of laser systems used for scientific research, X-ray equipment and signal transmission tools. Lab-grown diamonds used in the newest MRI scans help better detect cancers. And due to their unique density and ability to withstand high temperatures, lab-grown diamonds are projected to revolutionize optical transistors and processors, which will lead to faster computers.
