Natural cooling vacuum light guide tube and production method

The invention relates to the technical field of vacuum light guide tubes, and discloses a natural cooling vacuum light guide tube and a production method. The natural cooling vacuum light guide tube comprises a cylindrical tube body made of quartz glass, and the upper plane sealing glass and the lower plane sealing glass are formed at the two ends of the tube body respectively; the tube wall of the tube body is respectively perpendicular to the upper plane sealing glass and the lower plane sealing glass, and the tube body is matched with the upper plane sealing glass and the lower plane sealing glass to form an internal vacuum cavity. According to the natural cooling vacuum light guide tube and the production method, the problem that components are damaged by high-temperature heat energy in the focused light transmission process in the prior art is solved. 本发明涉及真空导光管技术领域，公开了一种自然降温真空导光管及生产方法，自然降温真空导光管包括由石英玻璃制成的圆柱状的管体，所述管体的两端分别成型有上平面封口玻璃和下平面封口玻璃，所述管体的管壁分别与上平面封口玻璃和下平面封口玻璃相垂直，所述管体与上平面封口玻璃以及下平面封口玻璃配合形成内部真空腔。本发明提供的
