Abstract

In the image capturing apparatus, the optical path difference producing member is disposed on the second optical path. Thereby, the amount of light for imaging an optical image which is focused at the front of an optical image made incident into the first imaging device (front focus) and an optical image which is focused at the rear thereof (rear focus) by the second imaging device can be suppressed to secure the amount of light on image pickup by the first imaging device. Further, in the image capturing apparatus, at least one of a position of the first imaging region and a position of the second imaging region on the imaging area is changed, thus making it possible to easily adjust an interval between the front focus and the rear focus. It is, thereby, possible to detect a focus position of the sample at high accuracy.
