摘要	PURPOSE:To eliminate the need to adjust the optical axis to a laser diode and to improve the efficiency of inspecting operation and the accuracy of measurement by combining and uniting a large-diameter handle fiber, a long-focus lens, and a short-focus lens. CONSTITUTION:The laser diode 1 as an object of inspection is fitted nearby the incidence port 2a of the large-diameter handle fiber 2 and light is emitted by an external power source, made incident on the incidence part 2a, and projected from a projection port 2b on the other end surface. A collimator lens 3 with long focus (f1) is provided behind the handle fiber 2 to make the incident light parallel. The spherical lens 4 with extremely short focus (f2) is provided behind the lens 3 and the incident light is made incident on a small-diameter photodetector 5 through this lens and converted here into an electric signal, which is sent to a characteristic inspecting device. Those handle fiber 2, lens 3, lens 4, and photodetector 5 are coupled in one body while their optical axes are aligned with one another.
其他摘要	用途：通过组合和组合大直径手柄光纤，长焦镜头和短焦点，无需调整光轴到激光二极管，提高检查操作效率和测量精度镜片。组成：作为检查对象的激光二极管1安装在大直径手柄光纤2的入射端口2a附近，并且光由外部电源发射，入射到入射部分2a，并从投影端口投射2b在另一个端面上。具有长焦距（f1）的准直透镜3设置在手柄光纤2的后面，以使入射光平行。具有极短焦距（f2）的球面透镜4设置在透镜3的后面，并且入射光通过该透镜入射到小直径光电探测器5上并在此转换成电信号，该电信号被发送到特征检查装置。。这些处理光纤2，透镜3，透镜4和光电探测器5在一个主体中耦合，同时它们的光轴彼此对准。
