Abstract: An object simulation unit for testing a camera objective has an optical axis and has a front side with respect to the optical axis at one side. The object simulation unit comprises a light exit surface at the front side of the object simulation unit, a coupling device that is adapted to couple the front side of the objection simulation unit to a light entry side of a camera objective, and a light beam generation device that has at least one light source and that is adapted to generate at least one light beam that passes through the light exit surface such that the at least one light beam apparently starts from a virtual object located at a distance from the light exit surface that is larger than the distance between the light beam generation device and the light exit surface. A diagnostic system may comprise such an object simulation unit.
