Abstract

The invention discloses an optical transmission window for an atomic clock; the optical transmission window comprises sleeves and optical lenses arranged in the sleeves; a body wall of each sleeve comprises a vertical sidewall portion and an extension portion positioned at the bottom end of the vertical sidewall portion and peripherally extended out from the bottom end of the vertical sidewall portion; the peripheral sidewall of each optical lens is hermetically fixed to the inner wall surfaces of the vertical sidewall portions of the corresponding body walls; the bottom of each optical lens is flush with the bottom edges of the vertical sidewall portions of the body walls. By modifying the structure of the optical transmission window, the need for batch coating of optical transmission windows is met, and the problem is solved that optical lenses in the multiple traditional optical transmission windows cannot be coated in batch at a time through an existing coating machine due to their structure limits.

Description

technical field [0001] The invention relates to the technical field of atomic clocks. More specifically, it relates to an optically transmissive window for an atomic clock. Background technique [0002] An atomic clock is an instrument that uses atomic energy level transitions to achieve high-precision time and frequency output. It is widely used in communication, navigation, timekeeping and other fields. Vacuum atomic devices are its physical core. In order to maintain ultra-high vacuum, the shell of vacuum atomic devices is generally welded with metal. When preparing atomic energy levels and exciting atoms to make transitions, it is necessary to transmit laser beams of a certain frequency into the interior of vacuum atomic devices to interact with atoms. In order to miniaturize and meet engineering applications, optical devices sealed by metallization are generally used. The transmission window is to coat the metallized layer on the side of the optical lens, and then use...
