CVD Diamond Product Line

In addition to the Shareholders' Meeting Results and Board of Director Appointments, the Company is also introducing its new line of chemical vapor deposition (CVD) diamond substrates for the infrared optics (IR) market. For more than 20 years, the Company has been producing CVD zinc selenide (ZnSe) and zinc sulfide (ZnS) for IR optical applications. The Company's expertise in CVD crystal growth accelerated the development program for synthesizing high quality CVD diamond material tailored specifically for optical applications. The Company's Wide Bandgap Materials (WBG) Group's experience with fabricating super-hard silicon carbide (SiC) facilitated the Company's development program for optically finishing our CVD diamond substrates. The Company also has many years of experience in coating customer-supplied diamond substrates with low absorption antireflective and partially reflective coatings for high power laser applications.

Diamond's unique properties provide solutions where other materials are not sufficient. Diamond has superior thermal conductivity for dissipating heat associated with high power lasers and electronics. Diamond's low thermal expansion coefficient and extreme hardness prevents typical mounting stress associated with extreme temperatures. With optical transparency ranging from UV to microwave wavelengths, diamond is ideal for a multitude of optical applications. Other applications where diamond's exceptional properties are beneficial include water treatment, medical dosimetry, high power and high frequency electronic devices, heat sinks and spreaders and surgical instruments.

The introduction of the CVD diamond substrates broadens the Company's diamond materials offerings to now include both optical and industrial grades. On July 1, 2009, the Company announced the formation of a joint venture with Beijing Supower Science and Technology Developing Co., Ltd. The new company, Langfang Haobo Diamond Co., Ltd., will produce industrial grade CVD diamond for cutting and wear applications.
