1. Oxide Materials Data Sheet

   Materion’s full range of inorganic oxide optical coatings provide the right materials for virtually any application. A variety of forms are available including granules, pellets & powders with extremely high purity levels.

2. Aluminum Oxide for Optical Coating

   Aluminum oxide is a versatile evaporation material suitable for coatings from the UV to the IR. With its role ranging from a high-index UV, to a mid-index or even a low-index material in the IR, usage of this material is key where a hard, clear and durable thin film is desired. While not so common in a fully reactive sense (from pure metal), careful use of plasma and make-up oxygen can increase material performance for sophisticated applications.

3. Hafnium Oxide for Optical Coating

   Hafnium Oxide is a high melting refractory oxide which can be used to satisfy designs ranging from UV to the IR, with less absorption and higher adhesion than other oxides. While originally pioneered for high laser induced damage threshold (LiDT) designs in UV, Materion’s evaporation grade hafnium oxide can benefit from ion assisted deposition (IAD) or post-deposition annealing to optimize performance. The unique oxygen transport and innate zirconium levels of the element make choosing the right form and approach critical for each application.

4. ITO Tin-Doped Indium Oxide for Optical Coating

   While the majority of indium tin oxide (ITO) is sputtered, in classical optics there remains strong demand for ITO as an evaporation material, at both its standard 90:10 ratio and at several key custom mixtures, depending on function of the layer and the substrate applied. Conventional wisdom states ordinarily high substrate temperatures are required for ideal transmission and sheet resistance attributes, but recent advances in plasma assistance with PVD and target technologies keep this compound fresh and relevant for both traditional as well as new applications.

5. Tantalum Oxide for Optical Coating

   As the industry looks ahead to 5G technology , it is easy to forget how the industry was able to move beyond copper and into the modern age of telecommunications. With this kind of innovation , tantalum pentoxide continues to be the high-index material of choice for many visible and near-infrared designs that benefit from its hardness, transparency, and stability in both pocket and the field. Benefiting from ion-assisted deposition or reactive sputtering, these high-index layers enable high performing filters and anti-reflection coatings for optical components. This material is key to growth in manufacturing, microscopy, and the increasingly critical global communications infrastructure.

6. Titanium Oxides for Optical Coating

   Since the beginning of the optical coating industry, much work has been done with Titanium Oxides to facilitate their use as a high-index material for visible and IR coatings. Due to the multiple stable sub-phases of this chemical, Materion focused on producing several stable phases for the market. Each type is designed to stabilize coating runs, and allow for multiple reloading and oxidation schemes that suit numerous PVD platforms. Materion continues to produce key optical grade materials ranging from the full oxide to high-purity titanium metal.
