Observing object cover, interference observation container, interference observation device and interference observation method

摘要

To provide an observation object cover, container for the interference observation, interference observation apparatus, and interference observation method capable of implementing interference observation under relaxed observation conditions.SOLUTION: An observation object cover 60, the observation object cover for interference observation, uses first light L1 and second light L2 having a coherent length longer than that of the first light L1 to acquire an interference light image of an observation object 3 by the first light L1, while adjusting an optical path length difference G on the basis of an interference result of the second light L2. The observation object cover 60 comprises: a transmission reflection section 61 that transmits the first light L1 and reflects the second light L2; a support section 62 that supports the transmission reflection section 61 such that a placement face 51a on which the observation object 3 is placed and the transmission reflection section 61 face each other at a prescribed interval A apart.SELECTED DRAWING: Figure 8
