The C12741-03 is a high-sensitivity InGaAs camera designed to operate in the near-infrared (NIR) spectrum from 950 nm to 1700 nm. Equipped with both an analog (EIA) output and a USB 3.0 interface, it enables 14-bit image acquisition and adjustable exposure times. These features make it well-suited for applications such as silicon wafer and device inspection, laser beam alignment, and solar cell evaluation.
