Calcium lanthanum sulfide is an infrared transparent ceramic with many desired properties including its high temperature optical and mechanical properties and its potential use in designing new multi-band optical components. However current production methods for calcium lanthanum sulfide are relatively immature and often contain impurities that limit optical performance of the produced powders. There is a significant need to develop and mature production processes for calcium lanthanum sulfide powders that provide batch-to-batch consistent stoichiometry and physical properties. Lynntech proposes an improved and efficient synthesis process to eliminate batch-to-batch variability and provide desired stoichiometry and physical properties for calcium lanthanum sulfide powders. It is the intent of this process to provide a scalable production process for calcium lanthanum sulfide powders to meet the development needs of optical component developers and future preparation and implementation of new optical components using these powders to maximize readiness in next generation infrared optical systems.
Benefit: Calcium lanthanum sulfide powders have dual-use potential for military and civilian-owned infrared sensing system markets. There is significant need to improve thermal imaging and night vision technology to augment surveillance capabilities and maximize soldier effectiveness in theater as well as improve personal and business security in the private sector. The technology can be scaled and adapted to a variety of system designs to accommodate user needs for security and surveillance. The new infrared transparent powder technology offers potential insight into the development and integration of new and improved infrared optical elements.
