Making Fluorescent Logos Visible with Dome Light
To verify the authenticity of products, logos, specific features or QR codes are often printed directly onto the product or packaging with fluorescent ink. During production, the prints invisible to the human eye must be checked for presence and completeness. With the help of a camera-based system consisting of a dome light and a smart camera, all common UV prints can be made visible, read and verified for authenticity. Operator safety is also ensured as the dome and filter block all direct UV rays.
