Slip Cast Spinel for Precision Conformal Sensor Windows
A need exists within the Navy for high quality, conformal optic sensor windows fabricated from MgAl2O4 spinel that exhibit excellent visible through mid-IR transmission. The implementation of spinel conformal windows is even more desirable considering its superior performance in demanding applications with sand and rain erosion and aero thermal heating. Ultimately, high quality metrology is required during and after grinding and polishing to ensure the best optical quality. To assist in the manufacture difficult to produce optical blanks, TA & T will demonstrate a near net-shape fabrication process for conformal MgAl2O4 spinel windows using an optimized slip casting process. The process methodology will be tailored to achieve the creation of a homogeneous, highly dense green body that can be densified to a high optical quality transparent ceramic. Optimax Systems will work with TA & T to help refine the blank manufacturing process and also ensure dense spinel toroidal blank usability and suitability in their system.
