An objective lens with magnetic and electrostatic focusing for an electron microscopy system is provided whose at least partially conical outer shape allows orienting an object to be imaged at a large angle range in respect of an electron beam, said objective lens exhibiting, at the same time, good optical parameters. This is enabled by a specific geometry of the lens elements. Furthermore, an examination for the simultaneous imaging and processing of an object is proposed which comprises, besides an electron microscopy system with the above-mentioned objective lens, also an ion beam processing system and an object support.
