This paper describes polished CVD polycrystalline diamond factors, several in extra of 1 mm in thickness, becoming made within the measurements and geometries needed For several infrared window and dome programs. For instance, one hundred mm diameter flats can now be fabricated routinely and 70 mm diameter hemispherical shells are increasingly being formulated. It is essential that the Attributes of the fabric are well suited for these types of purposes which paper describes the characterization of such Qualities. Information on the fabric's optical transmission Attributes, absorption coefficients (in a wavelength of 10.6 micrometers) and imaging Houses is introduced. The dielectric Attributes, for example loss tangent and permittivity, are assessed at microwave and millimeter wave frequencies and the suitability of CVD diamond for multispectral and multimode window applications is talked about.

During the absence of wafer material, the most crucial path to creating thin films has relied on ion bombardement. With this tactic, a flat diamond surface area is subjected to a big dose of superior Power (MeV) ion irradiation, causing a destruction layer normally several hundred nanometres down below the floor which can be selectively etched to peel off slim membranes28. Impinging ions, on the other hand, should journey from the product layer, leaving a large number of defects of their observe, thus degrading the fabric. When The difficulty might be circumvented by regrowth of pristine material29, high-quality things of ion-irradiation-fabricated membranes have so far been limited to Q≲20,000 (ref. 30)30.

The assortment and availability of diamond components is increasing, and recently continues to be extended to include CVD single crystal diamond. This paper opinions the standard of these supplies, taking a look at optical scatter and absorption close to one and 10 microns, along with their thermal and mechanical properties. We also discuss choice of correct grades and how they may ideal be integrated into demanding optical applications.

Unlike check here absorption and scatter, the thermal and mechanical Attributes of diamond are obviously independent of
