Pixel shift machine vision camera provides 260 million pixel resolution

The Vieworks VNP-29MC CameraLink industrial vision cameras utilise pixel shift technology to offer an extended resolution of 260 million pixels for ultra high resolution applications. These versatile cameras from Stemmer Imaging also deliver 29 megapixel resolution at a high frame rate of 5 fps under standard operation.

Its sensors are thermo-electric Peltier (TEC) cooled for improved sensitivity. The TEC maintains the operating temperature of the 6576 x 4384 pixel CCD up to 15 degrees below ambient. This provides extremely stable operating conditions, reducing noise and enabling exposure for a long period of time or at higher gain levels to increase camera sensitivity. This makes the cameras ideally suited to low light or low contrast level or non-uniform brightness industrial applications such as flat panel display inspection and microscopy.

Available in colour and monochrome versions, the cameras feature a nano stage pixel shift mechanism based on a precise piezoelectric stage. This enables the standard resolution to be extended by 4 times to 115 million pixels at 1.3 fps, or by 9 times to 260 million pixels at 0.6 fps. Colour versions provide true colour at full image resolution.

The VNP-29MC features a progressive scan interline transfer CCD imager with an integrated electronic shutter to provide excellent real time imaging performance. Camera features include flat field correction, field upgradable firmware
and pixel defect correction.
