Visum HSI™ - Hyperspectral Imaging System

Spatially resolved chemical vision. Hyperspectral imaging system (HSI) for physical chemical analysis, detection and sorting in real time. Make it perfect.



VISUM HSI™ is the most robust and versatile Hyperspectral Imaging System (HSI) on the market. It is designed to be integrated into any production line and provides pixel-by-pixel physical chemical information of everything that passes over the conveyor belt.


IRIS Technology is a pioneer in the design of turnkey hyperspectral imaging systems for in-line control of various industrial processes. The NIR or Vis-NIR combination of the Visum HSI™ hyperspectral imaging system allows it to adapt to the characteristics of each product and to the client's needs to perform multiple operations, including foreign body detection, quantitative and qualitative analysis and sorting of food, sorting of organic and inorganic waste, recovery and recycling of plastics, textiles, among other applications, industries and processes.
