| Reflection principle: |
At the reflection
principle, the product is illuminated
with white halogen light. The reflected NIR part
is detected by the NIR-sensor and
transferred to the diode array via an optical
fiber. |
| Transmission principle: |
At the transmission principle the white
halogen light streams through the product.
This only works, if the product is made of
transparent material. The halogen light
is received by the NIR-sensor (at the opposite
side of the lamp) and is transferred to
the diode array via an optical fiber. |
|
The evaluation unit and the NIR sensor are modular developed. Both are connected by an optical fiberglass cable. up to 100m in length.
