Cameras use sensors with polarized technology

SVS-Vistek has introduced new industrial cameras from the 'Exo' series, which work with the polarized sensor IMX253MZR from Sony.

The technical basis of this sensor is a matrix of polarizing filters with different orientations (0°, 90°, 45° and 135°), which are applied directly in each 2x2 pixel array. This has the advantage that the degree of polarization of the light, its polarization direction and the intensity of the polarized light can be measured and evaluated simultaneously with a single image without changing the lighting.

SVS-Vistek uses this sensor with 12 megapixel resolution in the exo253ZU3 industrial camera. The camera model is equipped with a USB3 interface and delivers a frame rate of 30 images/second. With 75 frames/second, the sister model exo250ZU3 enables more than double the frame rate for applications in which a resolution of 5 megapixels is sufficient. Both cameras are also available with 12 and 5 megapixel resolutions with a Gigabit Ethernet interface.

The use of sensors with polarized technology makes it possible to detect hidden material properties such as material stresses in plastic or glass.
