摘要： An objective for endoscopes with a lateral objective lens comprises an elongated prism having a convex proximal end surface and a distal end on which are joined by cementing after alignment on an optical axis, a diaphragm, a negative lens and optionally a wedge-shaped support, to form an indissoluble unit. The lens, the diaphragm and the support if present are provided with sections protruding radially beyond a desired periphery of the objective, which sections are ground off together to the dimension of the prism circumference, so that a rod-shaped objective unit is formed.
摘要翻译：具有侧面物镜的内窥镜的目的包括具有凸近端表面和远端的细长棱镜，其在光轴上对准后通过胶合而接合，隔膜，负透镜和任选的楔形支撑件，形成不溶解的单位。透镜，隔膜和支撑件（如果存在）设置有径向突出超过物镜的期望周边的部分，这些部分一起被研磨到棱镜周边的尺寸，从而形成杆状物镜单元。

摘要： A biconvex rod lens for the optics assembly of a medical or technical endoscope comprises of a light transmitting rod and a correcting lens cemented to one end of the rod. The rod is provided with at least one cylindrical collar which is of greater diameter than the adjacent lengths of the rod, for supporting the rod lens on the inner surface of an internal tube in the shaft of the optics assembly. In order to avoid shear forces arising in the cemented joint between the rod and the correcting lens when the shaft and thus the tube are bent when the endoscope is in use, the correcting lens and the rod have, in the region of the cemented joint, a smaller diameter than the cylindrical collar or collars. Fracture of the rod lens is there by avoided.
摘要翻译：用于医疗或技术内窥镜的光学组件的双凸透镜包括透光杆和胶合到杆的一端的校正透镜。杆设置有至少一个圆柱形套环，其直径大于杆的相邻长度，用于将杆透镜支撑在光学组件的轴中的内管的内表面上。为了避免当使用内窥镜时轴和管弯曲时在棒和校正透镜之间的胶合接头中产生的剪切力，校正透镜和杆在胶合接头的区域中，比圆柱形套环或套环更小的直径。棒状透镜的断裂是避免的。
