The Vieworks VNP-29MC CameraLink machine-vision cameras from Stemmer Imaging use pixel-shift technology to offer an extended resolution of 260 million pixels (MP) for ultra high-resolution applications. These cameras also deliver 29MP resolution at a frame rate of 5 frames per second (fps) under standard operation.
The VNP-29MC sensors are thermo-electric Peltier (TEC) cooled for improved sensitivity. The TEC maintains the operating temperature of the 6576 × 4384 pixel charge-coupled device (CCD) up to 15°C (27°F) below ambient temperature. This provides 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 suitable for low-light, low-contrast level or non-uniform brightness industrial applications, such as flat panel display (FPD) 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 115MP at 1.3fps or by 9 times to 260MP at 0.6fps. 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.
