Sensors Unlimited (part of Goodrich ISR Systems) provides the most effective solar cell inspection tools using shortwave infrared (SWIR) imaging products that detect light where silicon is totally transparent. Our powerful, sensitive SWIR cameras quickly identify cell defects and variations, as well as voids and abnormalities in silicon boules, bricks or ingots before they are sliced into wafers. Using forward-bias, they also reveal non-uniformities, cracks and defects within PV cells and across solar cell panels. Also effective with thin films and concentrated PV technologies, this early detection eliminates waste, and prevents unbalanced systems, ensuring delivery of the maximum power at the lowest cost. Get more out of your photovoltaics with SWIR.
We manufacture a complete line of SWIR imaging and detection products for machine vision, defense, and industrial applications. Our innovative InGaAs-based SWIR products include fast-framing high resolution cameras, SWIR linescan imagers, focal plane arrays, and more. They require no cooling, use standard optics and lens mounts, and feature CameraLink® outputs.
