Magnesium aluminate spinel is a durable electro-optical material with high visible through mid-IR transmission. Technology Assessment and Transfer (TA and T) reports on their efforts to integrate electromagnetic interference protection into spinel domes through the use of metallic grids. TA and T is developing an approach to embed noble metal EMI grids in spinel domes by encapsulating the grid with a germanate glass that has matching refractive index and coefficient of thermal expansion to spinel. Achievements to date and an outlook on this method as a viable manufacturing route are presented.
Magnesium aluminate spinel is a durable, broadband, electro-optical material that can be readily manufactured into
transparent domes for multimode seeker applications. Technology Assessment & Transfer, Inc. reports on the results of
its Army SBIR-funded research and development efforts to resolve manufacturing issues with regard to transparent
spinel domes. The specific areas of study have been cost, quality, and ability to scale up to full production. Alternative
manufacturing approaches were evaluated and compared. A clear path to full scale production has been identified.

Magnesium aluminate spinel is a durable, broadband, electro-optical material that can be readily manufactured into
transparent domes for multimode seeker applications. Actual spinel domes have suffered from manufacturing difficulties
and light-scattering inclusions. The program described herein has solved many of the difficulties to achieve better optical
properties and better process yields.
