摘要： A wireless fiber optic endface inspector includes a video microscope capable of wirelessly transmitting video streaming signal of endface image in real-time to a display device. The video microscope includes a microscope optical system, an adapting tip for interfacing an endface, an LED light source, a camera module for receiving and converting the endface image into video streaming signal, a Wi-Fi AP board, and a battery for supplying power. The video microscope may be constructed by adding a Wi-Fi AP board and a battery to a conventional inspector microscope. The display device has software for detecting when the endface is focused. Once the endface is focused, the display device emits an audio signal to alert the operator, who may then trigger the display device to analyze the endface image using an endface analysis software or save it to a folder, or transmit the image to a remote server.

摘要： An adapter for converting the field of view (FOV) of a connector endface inspector includes a housing with a front end for connecting with a fitting tip for interfacing with a fiber-optic connector, a rear end for connecting to a front portion of the inspector, and an internal light passage. A relay lens system including a front lens group and a rear lens group is embedded inside the housing across the light passage. To achieve a converted FOV, the optical working distance of the relay lens system is made the same as the optical working distance of the connector inspector's microscope objective, and the front focal length is made larger or smaller than the rear focal length of the relay lens system. The rear lens group may be embedded in a portion of the housing that may be detached and replaced to vary the size of the converted FOV.

摘要： A fiber optic connector endface inspection probe includes a microscope system, a camera module, and an image processing system. While the objective lens of the microscope system is being moved towards and past the focused position for the endface of a mated connector, either by manually turning a focusing knob in one direction or via an automatic transmission mechanism, the camera module continuously takes and sends endface images to the image processing system, wherein a microprocessor continuously monitors the sharpness of the endface images to acquire a focused image and analyze it to make an endface inspection pass/fail judgment, without using an external display to monitor the endface images. The microprocessor further comprises an embedded web server for converting endface images and inspection report into web pages to be transmitted by a wireless transmitter of the image processing system to external devices for optional monitoring or manual inspection.

摘要： A fitting tip of fiber-optic connector endface inspection microscope for inspecting angled connector endfaces includes a relay lens fixed inside its internal channel and is designed such that when it is received in an intended connector adapter and mounted to the inspection microscope, the normal line to the connector endface forms an acute angle γ with the optical axis of the relay lens; the ray exiting from the relay lens and conjugate to the ray along the normal line is aligned with the optical axis of the inspection microscope; and as a result the connector endface is imaged on an imaging plane within the focusing adjustment range of the inspection microscope. The best image of the connector endface is obtained when the angle γ is half of the inclined angle of the angled connector endface.

摘要： A connector inspector includes a microscope assembly, a supporting tray, a main frame, and a fitting tip. The microscope assembly is placed within the supporting tray with a bottom cylindrical protrusion inserted into a base plate of the supporting tray, and the supporting tray is coupled with the main frame with a pair of pivoting joints. The microscope assembly is horizontally biased by a spring and an adjusting knob, set between the main frame and the microscope assembly. The microscope assembly is vertically biased by a spring and an adjusting knob, set between the main frame and the microscope assembly. Thus, the microscope assembly may be swung to shift the imaging axis in two dimensions. The design of enables the inspector to be used with just one hand. See-through windows are formed on the sides of the fitting tip for monitoring the shifting of the imaging axis.

摘要： The fiberscope for inspecting and cleaning a fiber connector simultaneously includes a housing with a front panel, a microscope system, a connector holder mounted at a distance from the front panel for receiving a connector ferrule of a fiber connector, and a translation stage for moving the microscope system transversely to align its optical axis with the connector ferrule. The fiberscope further includes a hand knob attached to a fine screw through the connector holder for adjusting the vertical position of the connector ferrule, a mirror pivotally mounted between the connector holder and the front panel, an LED lamp, air nozzles attached to the front panel, and a cleaning air tube for supplying compressed air to the air nozzles. The cleaning air from the air nozzles spray sideways onto the fiber endfaces so that the cleaning air bounces off sideways to avoid secondary contamination.
