The GO-5100MP-USB machine vision camera from JAI A/S is built around Sony’s IMX250MZR polarized CMOS image sensor, offering 5.1 MP of total resolution and an innovative four-way polarized filter design creating a range of possibilities for imaging and analysis of objects and materials in industrial applications.
The camera features a full resolution of 2464 × 2056 pixels with a 2/3-in. optical format and pixel sizes of 3.45 × 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. Each block of four pixels can be used as a calculation block to determine the angle and intensity of light reflecting from objects, and 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 it can also enable analysis of material thickness, stress points, and other potential defects not detectable using standard machine vision techniques.
