Sensors and Cameras for Plant Phenotyping and Seed Testing

LemnaTec provides a wide range of approved sensors for all aspects of plant phenotyping and seed testing. Sensors and accessories, e.g. lamps and background materials, are tested in real research scenarios and the results are documented and supported by case studies and references.

The application of sensors for phenotyping aims at capturing dimensions, morphologies and colours of the samples. To address physiology, non-visible radiation such as near-infrared or fluorescence, is captured in addition. Spectral imaging and 3D scans deliver detailed insights in physiological and structural properties.

Data from sensors can be translated into traits or biological properties using appropriate mathematical models. Such models establish links between non-invasive measurements and actual plant characteristics.
