Abstract
An optical adaptor for an endoscope enabling an optically highly precise arrangement consists of a first frame member, a second frame member, and a distance restriction member. The first frame member is located at the distal part of the optical adaptor. A plurality of objective optical systems is stowed and held in the first frame member. The second frame member is located behind the plurality of objective optical systems. A relay optical system that transmits optical images formed by the objective optical systems and teams with an imaging optical system located in front of an imaging device in an endoscope to form an image transmission optical system is stowed and held in the second frame member. The distance restriction member is interposed between the first frame member and second frame member and thus sets the distance between the members to a predetermined value.
