Fusion series area scan 3CMOS multispectral camera

JAI has added a new area scan camera to its Fusion Series. The new 3-CMOS camera features three separate multi-spectral wavebands. The camera uses a dichroic prism that divides incoming light to three separate CMOS imagers while maintaining a common optical path.

This camera design enables the simultaneous capture of a 1.6-megapixel monochrome image plus 1.6 megapixel images from two separate near-infrared bands (740-800 nm and 820-1000 nm), all with perfect pixel-to-pixel alignment at up to 213 frames per second.

In addition to an increased frame rate compared to previous models, the new CMOS-based cameras have nearly double the sensitivity of JAI's original Fusion Series CCD models in the lower NIR band (700-800 nm) and approximately 20 percent more sensitivity in the upper NIR band, resulting in higher quality images under typical conditions, with less illumination needed to produce proper signal-to-noise ratios for inspection tasks.

By splitting the NIR information into “low” and “high” bands, the FS-1600T-10GE-NNM helps designers of multi-spectral vision systems to deliver better results by leveraging the different way that some biological substances (in life sciences applications), foods, chemicals, and other materials appear when viewed in different portions of the NIR spectrum.

The unique multi-spectral prism camera design, enables multi-spectral analysis to be easily applied to a wide range of machine vision inspection tasks, without the cost and complexity of multiple camera/lighting setups and without the added mechanical systems and motion challenges created by filter-wheel types of multi-spectral cameras.

The new FS-1600T-10GE-NNM model features the Sony Pregius IMX273 CMOS sensor offering 1.6-megapixel resolution (1440 x 1080 pixels) and a 1/2.9” optical format.

The high throughput of the new camera (213 frames/second) is supported by a 10GBASE-T (10 GigE) interface equipped with integrated auto-negotiation technology, providing automatic backwards compatibility to NBASE-T (5 Gbps and 2.5 Gbps) and traditional 1000BASE-T (1 Gbps) output for customers running vision applications on these lower-speed Ethernet standards. In addition to 8-bit output, the camera can provide 10-bit and 12-bit output, independently-selectable for the visible monochrome and the two NIR channels.

The 10 GigE interface complies with the GigE Vision 2.0 standard and uses a triple-stream approach over a single cable to efficiently provide the monochrome and NIR output for separate analysis or for combining on the host processor. The interface also supports the Precision Time Protocol (IEEE 1588) to enable network-level synchronization in multi-camera systems.

The FS-1600T-10GE-NNM has a size of 62 mm x 62 mm x 86.5 mm, with a lens mount supporting C-mount lenses.
