Sensors Unlimited – Goodrich ISR Systems has launched a compact SU1024LDM line-scan camera featuring high resolution, 1,024-pixel imaging in the shortwave infrared (SWIR).
The camera's square pixels are ideal for inspection of polished silicon blocks, ingots, or wafers, hot glass bottles, and for use on continuous-process lines that apply transparent coatings, which can be viewed 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.
The SU1024LDM is compact and robust (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. It 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 camera offers high quantum efficiency, wide dynamic range, and integrate-while-read acquisition. For added flexibility, the ruggedised housing supports an operating temperature range of -10 to +50°C. An optional 50mm f/1.4 lens designed specifically for the SWIR is also available.
In solar applications, the indium gallium arsenide (InGaAs) 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.
