In certain machine vision applications, the ability to see in- side an object is just as important as the ability to capture its outward appearance. For years, imaging professionals have struggled to combine imaging in both regions – but the solutions were either too costly or too difficult to de- ploy and maintain. The launch of JAI’s new multi-spectral camera ushers in a new era of affordable imaging.

The AD-080CL is a cost-efficient camera that simultaneous- ly measures visible and near-infrared (NIR) light spectrums through a single lens using two channels. The first channel has a Bayer mosaic color imager that only captures visible light, while the second has a monochrome imager for NIR light.

This multi-spectral imaging solution brings a new, essential dimension to a number of vision inspection applications. The visible light channel captures the red, green and blue bands of conventional imaging – or those visible to the human eye. The NIR channel, on the other hand, “sees” below the surface of organic and other materials to detect imperfections the human eye cannot see.

Many imaging applications require only monochrome cam- eras that work in the visible spectrum, or between 400 and 700 nanometers (nm). But certain applications require other parts of the spectrum to capture critical data. The quality of food, currency, and metals, for example, de- pends not only on their outward appearance – but also on the condition of tissue that may be below the surface or simply invisible to the human eye. Cameras that capture non-visible signals below 400 nm and above 700 nm are able to enhance details and see below the surface. The result is more thorough vision inspection, better quality verification – and, ultimately, higher quality products.

The advantages of 2-CDD technology compared to traditional multi-spectral technology

Although the imaging industry has used multi-spectral ap- plications for a number of years, the traditional solutions have remained costly and difficult to deploy.

One solution has been to simultaneously use two cameras: one for the visible spectrum and another for the NIR. Al- though seemingly simple from the user’s point of view, the two-camera solution is not only expensive, but also inef- ficient and potentially inaccurate, as the cameras need to be carefully and frequently aligned to ensure the same field of view. Moreover, working with twice the equipment

–two cameras, lenses, sets of cables, and so on – adds to the complexity of the application and decreases reli- ability.

Previously, the best alternative has been to use high-end multi-spectral 4-CCD: four-channel cameras that capture red, green, blue, and NIR spectrums. Although these com- plex cameras provide excellent results, they are expensive to buy and maintain.

New application possibilities thanks to easier deploy- ment, greater accuracy and lower costs

JAI’s new 2-CCD technology not only enables users to mea- sure both visual and NIR light with a single camera, but also offers easy set-up and alignment. Practical and cost- efficient, the AD-O80CL is ideally-suited for a large variety of applications, including:

•Inspection and sorting of food, such as fruit, vegetables, nuts, meat, and grains – including the ability to check the contents under printed packages

•Print inspection of packaging, such as cosmetics and food packaging

•Surface inspection of textiles and other flat products

•Print board inspection

•Electronics inspection

•Security print inspections including currency, checks, airline tickets, lottery tickets, and passports

•Advanced surface property and quality inspection of wood, metal, and other materials
