Abstract: CeraNova Corporation has been developing IR transparent ceramics since 2002, focusing in particular on transparent polycrystalline alumina. Knowledge and expertise gained in previous programs on densification of ceramics to transparency will be applied in the proposed program to edge bond plates of sapphire into large area IR windows. The joint itself is expected to have optical and mechanical properties essentially equivalent to sapphire. Evaluation of the joined area will include transmission in the visible and the IR, and strength testing at both room and elevated temperature.
Benefits: CeraNova's proposed proprietary technology will enable edge bonding of sapphire to produce large area IR transparent windows without any degradation in visibility in the region of the join. In addition, the joint region is expected to have mechanical properties at least equivalent to sapphire, including elevated temperature strength.
