Abstract

Six advanced MWIR transmissive materials have been selected for a comprehensive investigation to measure and compare their optical and mechanical properties. The six materials are: sapphire; A1ON (5A1N*9A1203); cubic zirconia (Zr02*9.4%mo Y203); spinel (MgO*A1203) fabricated by three processes; lanthana-doped yttria (Y203*9%La203) fabricated by three processes; and yttria (Y203). The following experiments have been performed on samples of each material: -thermal variation of transmittance -thermal variation of fracture strength - color center absorption A summary of the measured data is presented for each material.
