Two-CCD Camera Incorporates GigE Vision Interface

JAI has released a two-CCD camera featuring a GigE Vision interface. The AD-080GE camera is capable of simultaneously imaging visible and near-infrared (NIR) light spectrums through a single lens. Multi-spectral imaging is beneficial for many machine-vision applications, but traditional two-camera solutions have remained costly and difficult to deploy.

However, the AD-080GE single-lens two-CCD camera is claimed to provide simultaneous perfectly aligned images of both visible and NIR light spectrums. The AD-080GE features a two-CCD design, incorporating two 1/3in progressive-scan sensors (1,024 x 768 resolutions) mounted to a custom-designed optical prism. The camera runs at a frame rate of 30 frames per second in continuous operation.

The technology behind the AD-080GE is a manufacturing process developed by JAI that enables the high-precision bonding of image sensors onto the customised prism optics. According to the company, this delivers an industrial-grade, cost-efficient two-CCD solution, which enables the AD-080GE camera to be offered at a competitive price.

The AD-080GE is designed for a variety of applications where extended spectral imaging is required, such as for fruit and vegetable inspection, where the visible spectrum inspects surface colourisation while the NIR channel inspects below the surface of the object, revealing possible imperfections such as bruising and decay.

Other applications include the inspection of blister packs or other plastic film containers, where the visible channel enables the inspection of the print on the surface and the NIR channel enables the inspection of the contents.

The AD-080GE is suitable for traffic applications, the print inspection of banknotes, passports and tickets, electronic board inspection and the surface inspection of textiles. Each channel has separate gain and exposure control to optimise the signal-to-noise ratio at all times.

The camera is equipped with two GigE outputs, enabling the user to choose between single-cable operation or separate cables for each channel. Other features include partial scanning and vertical binning capabilities, as well as analogue video output to support auto-iris lenses. For the best imaging results, the camera features standard C-mount lenses, resulting in a high degree of lens flexibility and low production costs.
