Abstract

The invention discloses a high-leakproofness optical window and relates to the technical field of sensor sealing. The window comprises a cover plate and a through window body, and a baseplate is arranged on one surface of the cover plate; an opening is formed in the baseplate; a groove is formed in the cover plate; the groove is communicated with the opening; the through window body is fixed to the opening of the baseplate; the through window body is fixedly welded to the interior of the groove through welding flux. According to the high-leakproofness optical window, a groove-type design is adopted for an optical window placement area, it is guaranteed that the size of the product is reduced, the strength reliability of the optical window at high vacuum is guaranteed at the same time, andthe high-leakproofness optical window has the advantages that the eutectic welding strength is high, two-time sealing is achieved, the air tightness of the optical window is greatly improved, and theleakage rate can reach 5*10-10 pa.m<3> / s.

Description

technical field [0001] The invention belongs to the technical field of sensor sealing, in particular to a high-sealing light window. Background technique [0002] Sensors are now the mainstream of development. Most sensors require optical windows, and the interior of many sensor cavities is a high-vacuum environment, so there are high requirements for the sealing and strength of the optical window. However, the problems in the prior art are that the sealing performance of the light window is not high, and the bonding strength between the window and the cover plate is not high. Thus affecting the production efficiency of the product and the overall performance of the product, seeking to design a high-reliability light window is the key point for existing sensor companies to improve product performance. Contents of the invention [0003] The purpose of the present invention is to provide a high-seal light window. By adopting a groove-type design for the light window placeme...
