Sony unveils new polarised category of machine vision camera based on new IMX250MZR sensor

Sony Europes Image Sensing Solutions announced the XCG-CP510, the first in a new category of machine vision cameras.

The camera and category is based on Sony’s newly developed IMX250MZR global shutter CMOS sensor, which uses monochrome quad polarised filters to capture polarised light in four different angles.

To extract the best-possible image from the Sony sensor, the design of the XCG-CP510 module has been optimised by Sony’s industrial camera engineers and outputs 5.1 MP polarised B/W images at 23 fps, transmitted over a GigE interface.

The XCG-CP510 will be available in mass-production quantities from November 2018 and will be on public display at Vision Stuttgart, 6-8 November.

Additionally, an exclusive polarised-camera SDK will be made available to speed and simplify the development of polarised-light applications for this hardware.

Usage scenarios that would benefit the new camera category include stress inspection, contrast improvement, scratch detection and object detection / removal / enhancement from a single image capture. Sony is targeting a wide range of manufacturing applications – from glass inspection to electronics – as well as the ITS and security sectors. 

Arnaud Destruels, marketing manager, Sony ISS commented: “This continues Sony’s history of innovation and precision, with the sensor and camera engineers working closely to enable the best possible image to be created, while building in several beneficial features within a small footprint.” 

The small footprint of this cubic camera also includes multiple trigger modes: edge detection, pulse width detection, bulk trigger, sequential trigger, free set sequence and a burst-trigger function. Additionally the module can be fired via hardware or software triggers or via the IEEE1588 precision timing protocol, with the unit capable of acting as either a slave or dynamically assigned master device. 

The IMX250MZR sensor

The IMX250MZR, Sony’s newest image sensor, is a 2/3-type Pregius GS CMOS sensor and uses four different angled polarisers, with each pixel polarised for either 90o, 45o, 135oor 0o.A four-pixel (2 x 2) calculation unit is then created to capture light in four planes.

The camera also achieves a greater sensitivity with improved extinction ratio through Sony’s Wire Grid Polariser technology, which places the on-chip polariser beneath an on-chip lens. 

XCG-CP510 technical specifications

The XCG-CP510 outputs 23 2448 x 2048-pixel frames per second. The c-mount lens can be triggered using both hardware and software control. It consumes 3.0 W max from a +12V power supply and can operate from -5oC to +45oC, and between 20 and 80 per cent humidity. It has a vibration / shock resistance of 10 G / 70 G.

Dimensions: 29 x 29 x 42mm / Weight: 65g

It meets UL60950-1, FCC Class A, CSA C22.2-No.60950-1, IC Class A Digital Device, CE: EN61326 (Class A), AS EMC: EN61326-1, VCCI Class A and KCC regulations.

See it at Vision, Stuttgart

The XCG-CP510 and Sony’s cameras will be available to view throughout the Vision, Stuttgart trade fair. The Sony stand will be located in hall 1, stand C37.
