Abstract: In a Faraday microscope for examining specimens with stray magnetic fields in a reflected light beam path with a magnetic indicator film arranged in front of the specimen, the influence of the specimen on the indicator film is evaluated with the indicator film arranged as the termination of the microscope objective, the indicator film advantageously being arranged on an optically transparent substrate. The indicator film and substrate are taken into account in the optical calculation of the microscope objective.
