1. Product Introduction
The SWIR1503CU‑2.2 from Beijing AttosTek Co., Ltd. is a short‑wave infrared (SWIR) industrial camera based on a high‑performance InGaAs CMOS sensor. The camera covers a spectral range of 1200–2200 nm, with a peak quantum efficiency of 70% at 1900 nm. It features 0.33 MP resolution and a 15 µm pixel size. Equipped with a USB3.0 interface, the camera achieves a maximum frame rate of 270 fps to meet real‑time imaging requirements. It incorporates a TEC cooling module providing a 70°C temperature differential, and employs a global shutter to eliminate image tearing in high‑speed dynamic scenes. The SWIR1503CU‑2.2 camera is specifically optimized for deep‑infrared applications such as moisture detection, plastic sorting, mineral analysis, and environmental monitoring.

6. Application Cases
The SWIR1503CU‑2.2 is optimized for applications such as moisture detection, plastic sorting, mineral analysis, and environmental monitoring. It visualizes moisture content with high contrast for agricultural and food quality inspection. In the recycling industry, the camera distinguishes between plastics, cotton, and leather for automated sorting. In geology, it captures clear spectral signatures for efficient mineral analysis. The camera can also detect environmental pollutants that are invisible to visible‑light sensors.
