Compact InGaAs Line Scan Camera For Machine Vision: 1024LDM


Sensors Unlimited – A part of Collins Aerospace introduces their new LDM series of compact, InGaAs SWIR line scan camera for machine vision, sorting, & solar inspection. The 1024LDM line-scan camera features high resolution, 1024-pixel imaging in the shortwave infrared (SWIR). Its 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 ‘seen’ in the SWIR spectral region.

In solar applications, the new 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.

LDM Compact InGaAs Linescan Camera Features:

  • High quantum efficiency and dynamic range
  • Integrate-while-read snapshot acquisition
  • 45,956 lps for 1024 pixels over a 25 mm width
  • Wavelength response over 0.8 µm to 1.7 µm
  • 25 µm pixel pitch with the aperture height of 25 µm sharply defined by a photomask
  • 14-bit base Camera Link® compatible output and control
  • Operating temperature range of -10 to 50°C
  • Mounts easily to spectrometers due to 5.7 mm image plane depth and O-ring light seal
  • Mounts easily to optics benches or MV systems with tripod, front or side fastener hole patterns
  • Optional adapters for F-mount or C-mount, lenses (C-mount lenses may not fully illuminate the full width of the 25.6 mm wide arrays)
