JAI's AD-080GE is prism based 2-CCD progressive area scan camera capable of simultaneously capturing visible and near-infrared light spectrums through the same optical path using two individual channels.

The first channel has a Bayer mosaic color imager that captures visible light, while the second channel has a monochrome sensor for capturing near infrared light.

The AD-080GE camera is designed around Sony’s ICX-204AK & Sony ICX-204AL progressive scan CCD sensors (1024 x 768 pixels) delivering 30 frames per second in continuous operation. Using partial scan, the camera can achieve faster frame rates up to 85 fps.






JAI prism based 2-CCD multi-spectral camera technology

The prism inside the AD-080GE camera splits the light in two channels. The visible light channel captures the red, green and blue bands of conventional imaging. The near-infrared channel “sees” below the surface of organic and other materials to detect imperfections the human eye cannot see.

The camera features built-in pre-processing functions which include blemish compensation, shading compensation, Bayer to RGB interpolation, LUT/gamma correction and knee control.

The GigE Vision interface is selectable to 8-bit, 10-bit or 12-bit (packed) output for the NIR channel, 8-bit, 10-bit or 12-bit output for raw Bayer output and 24-bit or 30-bit for the RGB interpolated output. The camera features standard C-mount lenses, giving a high degree of lens flexibility.

JAI’s unique manufacturing process enables high-precision bonding of 2 image sensors onto in-housed designed prism optics. True multi-spectral information is secured from each channel, as the visible and NIR spectra are separated by the dichroic coatings of the prism.  (The separation wavelength is 760 nm).

Separate exposure times for each channel allow mutual adjustment without changes in gain, maintaining a consistent signal-to-noise ratio. The camera integrates seamlessly with the GigE Vision interface. (The camera is also available with Camera Link interface).

A comprehensive software control tool and development kit (SDK) for Windows is available. (32 bit “x86” and 64 bit “x64” - see SDK download page for details).

Dimensions in mm (Height x Width x Length): 55 (H) x 55 (W) x 98.3 (L) mm

Typical applications
The new camera is an excellent substitute for two-camera solutions, which are both more expensive and difficult to deploy/align.

The multispectral camera from JAI is designed for various applications. For some applications a perfect overlap of the two images, the visible image and the NIR image, helps simplify the application.

One example is when the object of interest has a certain size, e.g. a fruit or a number of fruits, resulting in different focus distances for each surface point – such an image task can only by multi imagers be handled easily with pixel to pixel alignment which is the case for JAI’s prism based cameras.

For other applications simplicity – one camera, one lens, one power supply, one set of cables, simple light source setup - makes a world in difference.

A typical application is fruit and vegetable inspection where the surface is checked via the visible spectrum channel, while the damages below the surface are inspected with the NIR channel of the camera. It is also useful for separation of food and non-food objects (e.g. stones or plastic items).

The AD-080GE can be very useful for inspection of medical blister pack or other plastic film containers. Again, the visible channel inspects the print on the surface and the NIR channel inspects the contents. 

Other important applications include print inspection of banknotes, passports and tickets, electronics inspection, wafer inspection and the surface inspection of textiles, wood and metal.
