Abstract: A protective cap for cylindrically mounted optical elements includes a retaining ring which is placed on a cylinder ring so as to be rotatable. The retaining ring covers the circumferential surface of the cylinder ring in a form-fitting manner. A latching mechanism having a latching element which engages in the latching mechanism in a force-fitting or form-fitting manner is present between the cylinder ring and retaining ring. The latching element is releaseable by an actuating element which is mounted on the retaining ring. A folding hinge for fastening and moving a protective cover from a covering position into a spatially fixed open position is present on the retaining ring.

Abstract: An optical assembly includes a connecting bridge to link up two autonomous optical units. The optical units are electronically connected to an analyzer. The connecting bridge is fitted each time with at least one coupling for each optical unit, said coupling making it possible, besides a mechanical coupling action, for the transmission of electronic signals and/or setting up an electric connection.

Abstract: The invention relates to a connecting bridge to connect two optical units. This connecting bridge is fitted in each case with at least one coupling for each optical unit making possible, besides mechanical coupling, also transmitting electronic signals and/or setting up an electrical connection.
