Sensors Unlimited – Goodrich ISR Systems’ compact and rugged SU1024LDM line-scan camera features high resolution, 1024-pixel imaging in the shortwave infrared (SWIR).

The camera’s square pixels are suitable for inspection of polished silicon blocks, ingots or wafers, hot glass bottles, and for use on continuous-process lines that apply transparent coatings that can be ‘seen’ in the SWIR spectral region.

The innovative square pixel design ensures that the pixel height is sharply defined by a metal mask, providing better uniformity of response and improved measurement accuracy for the object being imaged.

In solar applications, the indium gallium arsenide (InGaAs) line-scan imager detects cracks, occlusions, inclusions and misalignments before further processing, eliminating the waste and expense of manufacturing defective solar wafers or cells.

Other applications include high-speed imaging of free-falling molten glass, fast absorption or emission spectroscopy for combustion research, moisture, lipids, proteins, or other molecular vibration bands in the SWIR, and on-line sorting of agricultural materials, food products, recycled plastic pellets and pharmaceutical products.

The SU1024LDM is compact and robust (only 76 x 74 x 61mm) and has mounting points on four of its six sides, making it easy to integrate into a processing line or machine-vision system.

Goodrich’s new camera features a 14-bit base Camera Link interface, flexible triggering and line rates up to 46,000 per second for its 1,024 pixel width.

The SU1024LDM offers high quantum efficiency, wide dynamic range and integrate-while-read acquisition.

For added flexibility, the rugged housing supports an operating temperature range of -10 to +50C.

An optional 50mm f/1.4 lens designed specifically for the SWIR is also available.

Goodrich ISR Systems will premier the new SU1024LDM camera at booth 419 of Automate 2011, taking place at McCormick Place North, Chicago, Illinois, from 21-24 March 2011.
