Prism-based 4-CCD color line scan camera. Simultaneous separate imaging of R, G, B + NIR light data.

The SW-2001Q-CL is a prism-based 4-CCD color line scan camera providing simultaneous separate imaging of red, green, and blue, plus near-infrared light data.

The camera features a beam splitter prism with hard dichroic coatings incorporating four precisely pixel-to-pixel aligned CCD sensors.

R, G, B and NIR light spectrum bands are captured simultaneously in four separate channels through the same optical path. This combined RGB/NIR camera technology makes it possible to identify an even wider set of defects on inspected objects.

The incoming light is split into 4 spectral bands (RGB + NIR) with perfect pixel-to-pixel alignment. The Red, Green, Blue and Near-Infrared pixels see exactly the same point on the object  at all times.

Each of the four CCD sensors provides 2048 linear pixels with a pixel size of 14 μm x 14 μm square. The camera runs at a maximum scan rate of 19048 lines per second with a 40 MHz pixel clock, delivering a high signal-to-noise ratio of 58dB.




SW-20001Q-CL image example:
Inspection of red beans. Foreign objects are clearly seen via the NIR channel - left image. Foreign objects with lighter color tones (in this case a  yellow pebble) are better disclosed via the RGB channels show in the left image.


This makes inspection systems built with JAI’s prism-based cameras faster and easier for end-users to setup, calibrate and maintain, offering precise image alignment and precise color registration.

A number of built-in pre-processing functions are available including flat-field correction, gamma/gain correction and manual/automatic white balance. With the gamma/gain correction function the user can take full advantage of the sensors’ dynamic range to optimize the image. Gamma/gain correction, flat-field correction, as well as the electronic shutter can be set individually for the red, blue, green and NIR channels.

The SW-2001Q-CL features three shutter operating modes, including a pulse width control mode, providing users with substantial flexibility in operating the camera. The camera outputs 4 x 8 bits or 4 x 10 bits through a Camera Link interface. A binning function can combine the values of two adjacent pixels at the output stage resulting in double sensor sensitivity.

Just like JAI’s other line scan cameras, the SW-2001Q-CL undergoes extensive shock and vibration testing to maximize its ability to withstand the rigors of industrial environments. Specifications include 50G shock testing and 3G vibration testing.

A ridged housing design provides maximum surface area for heat dissipation resulting in excellent temperature management and optimal image quality.

SW-2001Q-CL is available with M52 mount (standard) or Nikon F-mount (optional).

Line scan application examples:

- Fruit and vegetable sorting. Inspecting colors, ripeness, damages, signs for early decay and foreign objects (e.g. stones, leafs etc).

- Food inspection (e.g. frozen food, rice grains, coffee beans, peas, cereals, tea and tobacco).

- Web inspection (Wood, textile, paper, glass).

- Tiles inspection (Inspection of colors variations and imperfections in glaze).

- 2D print inspection - magazines and currency. (Currency: simultaneous inspection of color correctness, water marks and security features woven into the bank notes).

- 3D print inspection (inspection of labels on cylindrical items like cans, bottles, pens etc. or rotating objects).

- Surface inspection of flat panels/displays looking for scratches and defective screen pixels.

- PCB inspection (Inspection for imperfections in circuit layout etc.).

The advantages of JAI’s prism-block technology:
The camera’s prism-block technology enables users to avoid the complex alignment and encoding issues associated with tri-linear line scan cameras, especially those related to off-axis viewing, variations in conveyor speeds, surface undulations, or objects that roll or move as they pass through the camera’s field of view.

In other words, the SW-2001Q-CL delivers high quality and perfectly aligned line scan images independently of the viewing angle to the inspected object, independently of variations on conveyer belt speed and independently if objects have a wavy or curved texture.
