Sensors Unlimited – Goodrich ISR Systems has developed a high-resolution, line-scan InGaAs camera, the SU1024LDM, which offers 1024-pixel imaging.
It is designed for use in short-wavelength infrared (SWIR) range and is ideal for solar inspection and machine vision applications.
The square pixels in the camera are ideal for inspecting ingots, silicon blocks and wafers. They can be used to monitor continuous-processes with transparent coatings visible in the SWIR spectral range. Defined by a metal mask, the square pixels provide a uniform response and enhanced accuracy in the measurement of the objects which are subject to imaging.
Measuring 76×74×61 mm, the line-scan camera comes with 4 mounting points, aiding its integration into a machine vision or process line system. The camera has line rates of up to 46,000/s and is equipped with a 14-bit base Camera Link interface with a flexible trigger. The SU1024LDM camera also offers a wide dynamic range, high quantum efficiency and features an integrate-while-read functionality.
The robust housing supports its operation in temperatures ranging between -10°C and 50°C. A 50 mm f/1.4 lens designed solely for use in the SWIR range is also available.
The camera can detect misalignments, occlusions, inclusions and cracks in solar applications before further processes are carried out, thus avoiding the cost of producing defective solar cells.
The high-speed camera can also be used for sorting food products, agricultural material, pharmaceutical products, recycled plastic pellets and in imaging of emission spectroscopy for combustion research, free-falling molten glass, lipids, proteins and moisture in the SWIR spectral range.
