Sensors Unlimited launches SWIR line-scan camera for machine vision, sorting & solar inspection

Sensors Unlimited — Goodrich ISR Systems of Princeton, NJ, USA has launched the SU1024LDM indium gallium arsenide (InGaAs) line-scan camera, featuring high-resolution, 1024-pixel imaging in the shortwave infrared (SWIR).

Its square pixels suits inspection of polished silicon blocks, ingots or wafers, for example, as well as use on continuous-process lines that apply transparent coatings which can be ‘seen’ in the SWIR spectral region. The 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, says the firm.

The SU1024LDM is compact (just 3” x 2.9” x 2.4” deep, i.e. 76mm x 74mm 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. The new camera features a 14-bit base Camera Link interface, flexible triggering, and line rates up to 46,000 per second for its 1024-pixel width. The SU1024LDM offers high quantum efficiency, wide dynamic range, and integrate-while-read acquisition. For added flexibility, the ruggedized housing supports an operating temperature range of –10ºC to +50ºC. An optional 50mm f/1.4 lens designed specifically for the SWIR is also available.

In solar applications, the new line-scan imager detects cracks, occlusions, inclusions, and mis-alignments 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.

Goodrich ISR Systems will premier the new SU1024LDM camera in booth 419 of the Automate 2011 event in Chicago (21–24 March).
