Abstract
In order to enable an endoscope to be made at a low cost and to provide the endoscope capable of effecting uniform illumination up to the peripheral regions of even a wide visual field without loss of the amount of light, the attachment for endoscopes is removably mountable to the forward end of the endoscope and comprised of an observation optical system and a light-guide member having a light-incidence end surface facing the illumination optical system of the endoscope for receiving a light coming therefrom and a light-emitting end surface having a shape different from that of the light-incidence end surface for emitting the above-mentioned light toward an object under observation.
