TELEVISION CAMERA TUBE |
摘要 |
In order to avoid picture disturbances by electric charging phenomena on the tube wall in a camera tube in which no target material is present on the inner wall of the cylinder tube, the tube wall is provided with a surface potential stabilizing material between the window connection and the mesh electrode of the camera tube. This stabilization can be realized by way of a local cover layer having the desired electric conductivity or secondary emission properties, or by locally adapting properties of the glass of the tube wall thereto. |
