An adapter is useful with a sample holder of a microscope. The adapter has at least one support region for reproducibly orienting the adapter in a mounted state in a sample holder support. The adapter also has a first coupling point for detachable connection to a coupling structure of a sample holder on one side, and a second coupling point for detachable connection to a coupling structure of a sample manipulator on a side of the adapter opposite to the first coupling point. The adapter is useful with the sample holder, a sample chamber, a microscope and a method for arranging a sample in a detection beam path of a microscope.
