The Mini Quantum Sensor LS-C is a miniaturised and flat sensor that can be placed close to leaves in small spaces, for example within cuvettes. The LS-C measures photosynthetically active radiation (PAR).
The LS-C is well suited for light incident perpendicular to the surface between -30° and +30°. For a completely cosine-corrected sensor, see MQS-B.
