Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a light source device, a detection unit, an optical system, an endoscope, and an industrial microscope, whereby the matter of light emitted from a light source leaking to the outside when a light guide member is not connected to a connection part can be suppressed. A light source device (2) comprises a connection part (265), a light source, a lever member (271), and a detection unit (272). The connection part (265) detachably connects a light guide member. The light source emits light that is made incident on the light guide member connected to the connection part (265). The lever member (271) displaces according to the presence or absence of a connection of the light guide member to the connection part (265). The detection unit (272) detects displacement of the lever member (271) and outputs a detection result.
