Detection of a fluorescent seam on a fabric A fluorescent seam is used in the textile industry to mark the junction of two fabrics; the seam can be fluorescent in orange or yellow and should be detected with an optical sensor. |

Presence control of plaster in a transparent plastic bag The presence of plaster in a transparent plastic bag should be controlled. At this, a part of the plaster is fluorescent if UV light is used. |

Detection of glue on a plastic film The presence of a glue layer on a plastic film should be detected. Almost the whole width of the plastic film should be controlled. The glue is slightly UV fluorescent, whereas the plastic film is UV neutral. |

Fluorescent label detection on metal foil packages The presence of paper labels on the front- as well as on the backside of golden and silver colored metal foil boxes should be detected. At this, the basic material of the paper labels is fluorescent, thus a UV – color sensor should be used. |

|
Detection of a fluorescent mark on a metal sheet matrix A fluorescent mark on the top side of a metal sheet matrix should be detected. |

Leak detection of welding lines on dish washers Leaks should be detected on welding lines of dish washers. At this, a robot equipped with a spray nozzle sprays a fluorescent liquid into the inner chamber of a dish washer. If leaks are present in the welding line, the fluorescent liquid flows through these leaks and can be detected with a fluorescent color detector. |

Färgdetektion av fluorescerande vätskor och färgmarkeringar De givare som för närvarande har funnits på marknaden för fluorescerande detektion har bara känt av intensiteten av det fluorescerande objektet men inte detekterat färgen. De har även haft svårt att detektera svaga objekt eller på avstånd mer än 80 mm. Dessutom känsliga för omgivande ljus. För dessa applikationer ska en färggivare för fluorescerande färg användas för säker detektion. Color differentiation of fluorescent liquids and marks Available fluorescent sensors so far detect only the intensity of a fluorescent object but not the color. Furthermore these sensors have a problem to detect very weak fluorescent objects or fluorescent objects at a distance more than 80mm and additionally they are sensitive against ambient light. For the purpose of fluorescent color mark detection a color sensor for fluorescent colors should be used. |
