| description | The invention is directed to a viewing glass having a transparent pane and a pair of flanges. In order to facilitate simple manufacture of the viewing glass, it is proposed that the pane be arranged in an inside step of the one of the flanges and be surrounded by an O-ring for producing a vacuum-tight connection. The edge of the pane and the step of the flange preferably have corresponding frustoconical surfaces. |
