Problems solved by technology

The optical precision of the light-transmitting surface achieved by micromachining is low, and there is an instantaneous high temperature in the bonding process, and stress is easily generated in the material during the cooling process. The gas and atomic components in the gas chamber are impure, which affects the final accuracy of subsequent devices
Therefore, it is difficult to meet the technical requirements of high-precision atomic devices for gas chambers only by improving the process on the basis of existing technical solutions. It is necessary to design a new glass bulb manufacturing method to complete high-precision, low-stress, high-purity gas chambers. make

Abstract

The invention belongs to the technical field of atomic air chambers, and specifically relates to a manufacturing method for a micro-miniature atomic air chamber. The method comprises steps of material selecting and cutting, assembly polishing, assembling, surface polishing, exhaust pipe installation, and subsequent processing. The technical problem the method solves is that an atomic air chamber manufactured by an existing manufacturing method for a micro-miniature atomic air chamber cannot satisfies high-precision, low-stress, and high-purity technical requirements of a high-precision atomic component on the air chamber. The method realizes manufacturing of an air chamber glass bulb in high optical quality of a light transmission surface, low stress, and high air tightness.
