ABSTRACT:
An electro-optical transducer which encompasses, within a vacuum tube, a constructional element having an alkali metal and a constructional element having a semi-conductor. The semi-conductor constructional element is rendered insensitive with respect to alkali metals. This is achieved in that the surface of the semi-conductor is at least partly covered with a layer or coating of polyimide.
