The PL-D755MU-POL 5.1Mpixel polarisation machine vision camera from Pixilink, based on the Sony IMX250MZR image sensor, offers broader visual detection and characterisation of material properties and improved performance over conventional sensors. It is ideal for inspection of high-reflection or low-contrast surfaces in applications such as parts inspection, strength/stress testing, scratch inspection and biometrics.
Sony’s IMX250MZR 3rd generation Pregius CMOS global shutter sensor features an innovative pixel-level quad polarisation filter technology, where four polariser positions, one per pixel, are angled at 0, 45, 90 and 135°, to enable greater detection of both the amount and angles of polarised light across an image. This allows on-camera calculation of the angle, degree and strength of the polarisation. The monochrome camera offers 53frame/s, 2/3in sensor size, USB 3.0 interface with a global shutter for industrial applications.
By filtering unwanted reflections and reducing glare, imaging previously undetectable defects, such as scratches or stress on transparent, reflective or low contrast surfaces, is now possible.
