The company is developing strengthened Magnesium Aluminate Spinel (MgAl2O4) for transparent optical sensor windows. The two primary objectives in this project are scaling up size and strength of Spinel windows. This enables use of advanced sensor systems operating from the UV through the mid-wave infrared (MWIR). It improves situational awareness, enhances targeting and intelligence, surveillance and reconnaissance (ISR) operations, and enables multiple sensor systems to operate behind a single protective window. Spinel reduces the total cost of ownership through improving erosion resistance, increasing protection against runway debris, reducing replacement, and improving preventative maintenance operations. Spinel has other applications in transparent armor, missile domes, viewports, and potentially as solid state laser gain media and scintillators for medical, high energy physics, and detection of special nuclear materials.
