Abstract

Thermal electro-optical imaging systems require windows fabricated from materials that are not only transparent to infrared radiation but also possess adequate structural strength to successfully withstand loads imposed on them by operational scenarios. Optical grade mono-and polycrystalline germanium has found wide acceptance for applications in the 8 to 12 micron wavelength region where the windows are exposed to high pressure in the presence of moisture, or water. The paper addresses itself to physical properties of germanium and structural parameters of windows and their mountings that must be considered in the successful design of germanium windows for external pressure service.
