Connecting bridge for two optical units

A connecting bridge (10) to connect two optical units (110), comprising:

• at least one coupling (20) for each optical unit (110) to couple the particular optical unit (110) to the connecting bridge (10), said connecting bridge being fitted with both mechanical coupling elements (22) and electronic coupling elements (24) that are configured in a manner that the electronic coupling elements (24) set up electronic contact between the connecting bridge (10) and the particular optical unit (110) when the mechanical coupling elements (22) set up mechanical contact between the particular optical unit (110) and the connecting bridge (10),
• a connector (30) extending at least in segments between the couplings (20) and mechanically linking them to each other, and an analyzer (40) which is electronically connected to the electronic coupling elements (24) and can exchange electronic signals with them and/or can set up an electric connection between the electronic coupling elements (24) of the couplings (20).
