The camera features a full resolution of 2464 x 2056 pixels with a 2/3” optical format and pixel sizes of 3.45 µm x 3.45 µm. The polarization capabilities are derived from the sensor’s unique filter array, which consists of four separate polarizing filters – angled at 0°, 45°, 90°, and 135° - that have been arranged in a regular pattern across the sensor. Thus, each block of four pixels can be used as a calculation block to determine the angle and intensity of light reflecting from objects, as well as several other calculations. The use of polarization filters can not only mitigate reflections and hot spots, particularly when inspecting plastics, glass, and other shiny materials, but can also enable analysis of material thickness, stress points, and other potential defects not detectable using standard machine vision techniques.
The GO-5100MP-USB is equipped with a USB3 Vision interface enabling it to provide full resolution, 8-bit output at up to 74 frames per second. 10-bit and 12-bit output is also supported.
