Q1 : What imaging advantages does this camera have for moisture detection and agricultural/food quality inspection?

This camera can visualize moisture content with high contrast, making it useful for agriculture and food quality inspection. Water molecules have unique absorption features in the short-wave infrared (SWIR) range, especially around 1400 nm, 1900 nm, and 2200 nm, where there are characteristic absorption peaks. The SWIR1503CU-2.2 has a spectral response range of 900–2200 nm, which exactly covers these water absorption bands, allowing precise measurement and mapping of moisture content in crops and food. Specific applications include assessing moisture content and quality grading of grains, nuts, and fruits & vegetables, monitoring and controlling moisture during food processing, and tracking moisture changes during storage of agricultural products.

Q2 : 900–2200nm compared to 900–1700 and 900–1900: differences in applications for the same series of cameras?

Unique Advantage: Expands the long-wave range to 1900–2200nm, covering characteristic absorption peaks of mineral hydroxyls, deep moisture, plastic polymers, and oil stains. It performs significantly better than short-wave models in mineral analysis, plastic recycling, and fruit and vegetable moisture detection. Suitable Exclusive Industries: Geological core spectroscopy, thick plastic sorting, deep non-destructive fruit and vegetable testing, and monitoring oil pollution in factory areas.

Q3 : Which systems does the AttosView host software support, and what professional imaging features does it have built-in?

System Compatibility: Only Windows 7/10/11 64-bit systems; Built-in Full Features: Software and hardware dual trigger modes, auto/manual exposure, three-level gain switching, image vertical/horizontal flip, up to 12 sets of custom dark field correction, real-time histogram, profile line grayscale curve, pixel grayscale reading, custom area grayscale statistics, frame timestamp marking, hardware noise reduction, firmware online upgrade; supports batch recording of Raw/RGB images and is compatible with spectral data acquisition.
