近年来,医用光学仪器在不断增加,由于光学纤维的出现,使得人们有可能把它和光学镜头联系起来,深入到人体内部检诊疾病。下面介绍一下苏联最近研制的五胶合光学纤维内窥镜物镜,如图1所示。该物镜是由三个正透镜夹有两个负透镜构成的,孔径光栏胶在平板玻璃1上,将平板玻璃胶结在五透镜的小前片透镜上,光学纤维3胶结在五透镜的最后一片透镜的凸面上。直径为2.8毫米的内窥镜物镜结构参数如表1。
In recent years, the number of medical optical instruments has been on the increase. Due to the appearance of optical fibers, it is possible to link it with optical lenses and to go deep into the internal body to test the diseases. The following describes the Soviet Union recently developed five glued optical fiber endoscope objective lens, shown in Figure 1. The objective lens is composed of three positive lens sandwiched between two negative lenses, aperture diaphragm glued on the flat glass 1, the flat glass cemented on the five lens small front lens, the optical fiber 3 cemented at the end of the five lens On the convex surface of a lens. The diameter of 2.8 mm endoscopic objective lens structure parameters in Table 1.
