Manufacturing Methods & Technology Program, Zinc Selenide Blanks for Windows and Lens Elements.

Abstract

This program established a fully automated process for the chemical vapor deposition of zinc selenide blanks. Prior to the program Raytheon Company had an established production process for the fabrication of this material. Further, Raytheon Company had, on an experimental basis, determined that the process could be fully automated by replacing the internally housed zinc source system with an externally housed system that fed zinc into the furnace at a predetermined rate. This system was successfully used in the Pre-Engineering, Engineering, Confirmatory, and Pilot deposits to yield zinc selenide with good optical and mechanical properties. The program also demonstrated that this process significantly reduced the costs of standard type lens blanks. (Author)
