An index that is linked with focus adjustment is provided on the periphery of the field of view in which the object is attached, and configured so that it is easy to compare the length of the reference represented by the index and the size of the object. The purpose of this invention is to provide a length-measuring endoscope that can easily determine the size of objects.The present invention will be explained with reference to the drawings. This is an explanatory diagram for explaining the principle of 0. In the same diagram, an object 2Fi shown by an arrow mark on the moving blade of the objective lens thread 1 is mowed down at a position and size according to the distance 11 between them. 0 Same, same figure (IL) Fi, object 2
When the object 2 of the same size is located at a short distance, Figure (b) shows the case where the object 2 of the same size is located at a long distance.0 The optical image formed by the objective lens system l is composed of a relay lens system. The image transmission means 3 (shown as a single lens in the figure)
The information is transmitted to the eyepiece system 5kJ position along the original axis 4, and by adjusting the focus by finely moving the eyepiece system 5 back and forth along the original axis 4, the optical image is enlarged and clearly imaged. Therefore, as shown in Figure 2, for example, a crosshair is formed at the center and is formed at the top of the circular field of view, and there are usually identification indicators that can be used to determine the front and back of the film as well as the top and bottom. For example, during the above-mentioned focus adjustment, an indexing mechanism is provided that moves in conjunction with the same rotation, and the distance (length) between the inner indexing points is set to a length that depends on the distance at which the object is observed through the eyepiece system 5. To change the size according to K, the size of the observed object 2 is compared with the observed length between the indicators, regardless of the distance.
You will be able to know more.
