1. An imaging apparatus comprising:
a detector configured to detect a surface position of an object by receiving a second electromagnetic wave of which a wavelength is shorter than a first electromagnetic wave;
a focusing device configured to collect the first electromagnetic wave reflected on the object;
at least one memory and at least one processor which function as a control unit configured to control the focusing device such that a position based on the surface position is focused on; and
an image sensor configured to image an interior of the object using the first electromagnetic wave collected by the focusing device,
wherein the control unit performs at least processing to control the focusing device such that the interior of the object, which is more distant from the imaging apparatus than the surface position detected by the detector from the imaging apparatus by a predetermined distance, is focused on, and
the predetermined distance is a value greater than zero.
