An ocular attachment for an endoscope, in which the endoscopic image may be split into two images in each case by several adjacently positioned beam splitter elements which are displaceable transversely to the image axis, to which end, the one image may be transmitted to a first camera connector along the image axis acting as a first optical axis, and the other image may be transmitted to a second camera connector via an image ductor along a second optical axis. The degree of brightness of these two images may be adjusted by the beam splitter elements having different divisional ratios and held by a mounting, by placing one of the beam splitter elements in the beam path of the endoscopic image in each case, by displacing the mounting. An arrangement is also provided for supplying an undivided endoscopic image at will to the first or second camera connector.
In an ocular attachment for an endoscope, in which an endoscopic image may be split into two images by means of one in each case of several adjacently positioned beam splitter elements which are displaceable transversely to an image axis, one image being transmissible along said image axis acting as a first optical axis to a first camera connector and the other image being transmissible to a second camera connector via an image conductor along a second optical axis, to which end the degrees of brightness of both images being adjustable by means of the beam splitter elements having different transmission/reflection ratios and being secured in a mounting, one of the beam splitter elements being positionable in each case in the beam path of the endoscopic image by displacing the mounting, the improvement comprising means being provided in said mounting for supplying an undivided endoscopic image optionally to a selected one of the first and second optical axes.
An ocular attachment for an endoscope comprising a housing having means for forming a first image axis extending to a first connector, means for forming a second image axis extending perpendicular to the first image axis and extending to a second connector, said second axis intersecting said first axis, said housing having means for selectively positioning one of a plurality of optical elements at a point of intersection of the first and second axes, said optical elements including at least one beam splitter element and said optical elements including means for supplying an undivided endoscopic image to one of the first and second axes.
