Abstract

The invention discloses an optical transmission window for an atomic clock. The optical transmission window includes a sleeve and an optical lens set in the sleeve; a cylindrical wall of the sleeve includes a vertical side wall; The bottom end of the vertical side wall portion is an extension portion extending outward along the circumference of the bottom end of the vertical side wall portion; the circumferential side wall surface of the optical lens and the vertical side wall of the cylindrical body wall The inner side wall surface of the part is sealed and fixed; the bottom surface of the optical lens is flush with the bottom edge of the vertical side wall part in the barrel wall. By improving the structure of the optical transmission window, the invention is suitable for the batch coating of the optical transmission window, and solves the problem that the traditional optical transmission window cannot be used for multiple optical transmission windows at one time due to the limitation of its structure by the existing coating machine. The problem of batch coating of optical lenses in .

Description

technical field [0001] The present invention relates to the technical field of atomic clocks. More specifically, it relates to an optical transmission window for an atomic clock. Background technique [0002] Atomic clock is an instrument that uses atomic energy level transition to achieve high-precision time and frequency output. In order to maintain ultra-high vacuum, the shell of vacuum atomic devices is generally welded by metal. In the preparation of atomic energy levels and the excitation of atoms to make transitions, it is necessary to transmit a laser beam of a certain frequency into the vacuum atomic device to interact with the atoms. In order to miniaturize and meet engineering applications, optical metallization sealing is generally used. The transmission window is to coat the metallization layer on the side of the optical lens, and then use the brazing technology to weld the optical lens and the metal sleeve with solder (the melting point generally does not exc...
