Sweep+: prism, performance, precision

Based on a combination of JAI's well-known prism technology and CMOS sensors with large 20 µm x 20 µm pixels, the two new colour line scan CoaXPress cameras deliver the best-of-breed in colour reproduction, RGB colour alignment, edge sharpness, signal-to-noise ratio.

The cameras feature large-format sensors with 400 µm2 pixel area to collect photons. This large photon collection area, combined with large pixel quantum wells, provide an excellent signal/noise level and so maximizing the image quality.

Why prism technology?
Multiple CMOS line sensors are precisely aligned to a common optical path providing solutions that are easier to set up, with higher colour precision and less colour degradation over time than tri-linear or quad-linear color cameras.

The SW-2000T-CXP2 is a 3-CMOS sensor RGB camera featuring 3 x 2048 pixels with 2-channel CoaXPress interface, while the SW-2000Q-CXP2 (with 4-CMOS sensor technology) features a fourth imaging channel making it capable of capturing the NIR light spectrum simultaneously with the RGB light spectrums. The 4-CMOS model is also available with 2-connector CoaXPress interface.

Additional benefits of Sweep+
20 µm x 20µm pixels gives higher scan speeds
The high sensitivity pixels make the Sweep SW-models capable of capturing an acceptable exposure at 4 times the speed of a camera with only 10 micron pixels

Selectable resolution for flexibility
The cameras feature a selectable resolution making it possible to use it as a 2048, 1024 or a 512 pixel camera or any other resolution from 2048 pixels down to 128 pixels (256 pixels with binning).

Two sensor operation mode
The SW-models can run in two sensor modes – a higher dynamic range mode and a responsive mode.

Individual settings of shutter time
The shutter time for R, G, B and NIR can be set individually providing an opportunity to adjust the light collection amount for each individual colour band, to refine selected image details.

Ethernet port for remote settings
The cameras are equipped with an Ethernet port for remote settings, firmware updates and retrieval of documents such as manuals, from the camera. An internal web server in the cameras make embedded documents and firmware updates accessible via standard web browsers.

JAI lens technology for perfect match
Special JAI lenses are perfectly matched with JAI’s prism technology providing an even better image sharpness and image quality. Besides the JAI direct mount, the camera is also available with a normal F-mount.

No image distortion problems
The Sweep plus avoids colour anberrations seen with multiline linescan cameras. Halo effects, where the 3 colours are slightly mismatched in the final image occur to some extent in tri-linear colour line scan technology especially if the inspected objects have undulations or changing orientation (e.g., rolling, wobbling during inspection).

• Fruit and vegetable sorting. Inspecting colours, ripeness, damage, early decay, foreign objects

• Captures high resolution, full-field scans

• 2D colour print inspection - magazines and currency

• Web inspection (textile, paper, glass and film).

• Wood inspection (looking for wood structures like knots, grain and colour)

• Inspection and sorting of waste at recycle station

• Paint coat applications (checking colour correctness; even application on car bodies

• 3D colour print inspection (inspection of labels on cylindrical items or inspection of rotating/turning objects, where it is important to inspect all “angles” of an item)
