Abstract
An end face observation device () of this invention includes a first lens () including a missing portion () extending through in an optical axis direction, a light source () configured to generate light that irradiates an end face (A) of an observation target via the first lens, and an image capturing element () configured to receive an image of the end face of the observation target via the first lens. This can implement an end face observation device that integrates a structure configured to operate the end face of the observation target with an observation device configured to observe the end face by inserting the structure configured to operate the end face of the observation target into the missing portion of the first lens.
