Reflection and transmission VIS/NIR sensors
The modular system consists of a VIS or NIR sensor and an evaluation unit.
Depending on the application, two measuring principles are available:
- Reflection measurement: The product is irradiated with white halogen light or LED light. The reflected VIS/NIR component is detected and evaluated by the sensor. This method is particularly suitable for solid, liquid or non-transparent products.
- Transmission measurement: The product is irradiated with halogen light, which is only possible with transparent media. The penetrating light is received and evaluated by the sensor.
