What is Polarization?

Polarization is a integral property of light and is the phenomenon in which waves of light are restricted in direction of vibration. The majority of light sources, such as the sun, give off unpolarized light. Unpolarized light is vibrating in more than one plane. When we are polarizing we are in  process of affecting light so that the vibrations of the wave assume a definite form. For example we install polarized lenses or filters in front of the sensor to minimize glare from a shiny surface, so we can see impurities below or on the surface. See images below:

Benefits of Polarization?

  • Stress Inspection
  • Reduce Reflection
  • Improving Contrast
  • Scratch Inspection
  • Object Detection

The Basler Ace Series With Sony IMX250 Polarized Sensor

The Basler acA2440-75umPOL USB 3.0 camera with a MZR polarized Sony IMX250 CMOS sensor that delivers 75 frames per second at 5.0 MP Resolution. This camera offers superior image quality: high quantum efficiency, wide dynamic range, and extremely low noise.

With the addition of the polarized sensor , you are able to get the advantages of a polarized lens or filter without any additional cost or weight.

When this camera is used at the sensor’s full resolution, it can record at 75 frames/second. Also when it is  used at a lower resolution, the frame rate will increase. For example: 2048 x 2048 at 80.8 fps, 2448 x 1080 at143.7 fps, and 2448 x 480 at 323.3 fps. (Note maximum frame rate also depends on the output format, exposure time, and USB hardware.)

This is the Wilco Imaging GLR-ACA2440MZR-75UM is the Basler ACA2440-75umPOL with the sensor glass removed, that delivers 75 frames per second at 5.0 MP Resolution.

With the Sensor Glass removed, it is exceptional for laser profiling, interferometry, Ultra Violet applications.
