I. Product Introduction
The SWIR051AU from Beijing AttosTek Co., Ltd. is a short-wave infrared (SWIR) camera with high sensitivity, high frame rate, and excellent stability. It is equipped with a Sony IMX990 sensor, featuring 1.3 MP resolution, 5 μm pixel size, and 400–1700 nm spectral response. The built-in TEC cooling system provides a 30°C temperature differential, and the USB3.0 data interface achieves a full-resolution frame rate of up to 200 fps, with a dynamic range of 58.7 dB. It is suitable for application scenarios with stringent requirements for real-time performance and detail layering, making it an ideal choice for industrial inspection, scientific measurement, and high-end vision applications such as laser imaging, spectral analysis, haze penetration, and smoke and dust environments.
