To solve the problem of the low yield and the later failure of the soldering of Al2O3 sapphire optical filter and Kovar alloy,several influencing factors of the low field of the Al2O3 sapphire optical filter are analyzed and studied. Aiming at these influencing factors,the solutions are proposed and its reliability has been verified through the experiments.
