OBSERVATION TARGET OBJECT COVER, CONTAINER FOR INTERFERENCE OBSERVATION, INTERFERENCE OBSERVATION DEVICE, AND INTERFERENCE OBSERVATION METHOD

摘要

Provided is an observation target cover for interference observation using first light and second light having a coherent length longer than that of the first light so as to acquire an interference light image of an observation target by the first light while adjusting an optical path length difference based on an interference result of the second light, the observation target cover including: a transmission reflection portion that transmits the first light and reflects the second light; and a support portion for supporting the transmission reflection portion so that a placement surface on which the observation target is placed and the transmission reflection portion face each other with a predetermined gap therebetween.
