The infrared focus plane micro-dewar must have vacuum high air-sealed properties in order to be able to stand up to the demanding of vacuum longevity.In the manufacture course of infrared focus micro-dewar,laser welding is among crucial processes for the sake of obtaining low integral leakage.This paper reports on laser welding process characteristics of the infrared focus micro-dewar.
