Detecting pollutants, fluorescence brightening agents, and particles with the UV LED Detector

UV light is not only used for screening fake bills or ID cards, but also can be used for other multiple purposes such as detecting particles, pollutants, refrigerant leak, bodily fluid and finger prints, or fluorescence brightening agents.

The image above show soap and other pollutants on a front wall of a sink found by the UV LED Detector MP12t. Natural light cannot, but only UV light can check such marks.

The image above shows how the UV LED Detector MP12t detects fluorescence brightening agents. The left image turned blue as the paper contains fluorescence brightening agents, but the right image does not show any response as the paper does not contain any fluorescence brightening agents.

Fluorescence brightening agents are used in many consumer goods such as paper, soap, sanitary items, textile, plastic, and paint, and are known to cause various skin problems and digestion issues. In particular, toddlers who ha sensitive skin are recommended to use clothes, towels, and tissues that do not contain fluorescence brightening agents.

The image above shows how the UV LED Detector MP12t detects particles such as dust on an LCD sample. Since having particles significantly affect semiconductor and display process, thorough particle control is necessary.
