set with Fiber Illumination 1 Overview NanEye is a tiny camera module which consists of a CMOS image sensor with a footprint size of 1mm x 1mm and, optionally, an adapted miniature optics. The device is mounted on a flat ribbon cable measuring up to 2m in length. Other cable lengths measuring up to 3m are possible upon request. The Evaluation set consists of the NanEye base station which receives the NanEye sensors LVDS bit serial data stream and translates it to a USBII protocol that will interface over a standard USBII connection to a PC. The supplied viewer software controls the NanEye camera, and displays the video images. The fiber light source provides illumination over a 1mm diameter POF fiber to the tip of the camera Figure 1: NanEye evaluation set overview block diagram Date: 17/03/17 Version 1.0.7 Page: 4/21 Evaluation set with Fiber Illumination 2 Fiber optic light source Specifications PC Interface Protocol USB2 Programmable Unit FPGA – Xilinx Spartan 3E Power Supply Via USB 5V Dimensions Width 16 cm Hight 6,1 cm Length 20 cm Sensors 1 x NanEye 2D 1 x NanEye Stereo Table 1: NanEye Fiber Demo Kit Specifications Figure 2: NanEye Fiber Demo Kit The camera is at the distal tip of the cable. The light source is provided through fiber coupled LED and it is also on distal tip of the cable, in front of the camera.

It will be directly mounted on the image sensor and has its best focus position defined by design, so no mechanical set of focus is needed. The material is based on B33 (Borofloat glass). The design is made in such way that the surface towards the object is flat, so the lens performance is not influenced by the medium between the object and lens. Only the opening angle of the lens is reduced when the system operates in water.
