JAI has added four new prism-based colour line scan cameras to its Sweep+ series. Based on a combination of the company's prism technology, a specially optimised JAI lens and CMOS sensors with large 20 x 20µm pixels, the four new colour line scan cameras deliver high-end colour reproduction, RGB colour alignment, edge sharpness and impressive signal-to-noise ratios.
The camera models SW-2000T-CL and SW-2000T-CXP2 are three-CMOS RGB cameras featuring 3 x 2,048 pixels with Camera Link and two-channel CoaXPress interfaces, respectively.
The other two models, the SW-2000Q-CL and SW-2000Q-CXP2, have four prism-mounted CMOS sensors, with the fourth imaging channel designed to capture the NIR light spectrum simultaneously with the RGB channels. The four-CMOS models are also available with either Camera Link or two-connector CoaXPress interfaces.
The high sensitivity pixels make the Sweep SW-models capable of capturing an acceptable exposure at four times the speed of a camera with only 10µm pixels. The SW-models can scan up to 80,000 lines per second making them ideal in industrial applications requiring high speed process inspection. Additionally, the cameras offer a large 400µm2 light collection area per pixel, and large pixel quantum wells (with as much as 360k electrons).
The SW-models can run in two sensor modes – a higher dynamic range mode and a responsive mode. When set to the higher dynamic range mode, the quantum well will be filled up with as many as 360k electrons, providing images with higher signal-to-noise ratios and higher dynamic range. In situations where less light is available, the camera can be set to the responsive mode. In this mode, the camera is set to a smaller quantum well (60k electrons). This enables the well to fill faster under scarce lighting conditions enabling it to maintain its speed while providing a higher response on the greyscale.
The shutter time for R, G, B and NIR channels can be set individually providing an opportunity to adjust the light collection amount for each individual colour band, to refine selected image details.
