Fluorescence

- Principle -

Fluorescence is a physical property of specific photosensitive substances which can emit light when they are excited by another light. This light is absorbed in a specific UV wavelength (from 255 to 405nm) and then re-emitted at a visible wavelength (green, yellow...). This phenomenon allows the revelation of hidden code, bubble in coatings, specific inks...
UWAVE offers complete products in the UV range for manual or automated fluorescence works. Precise, compact & innovative LED lightings often replace old, huge & energy-consuming mercury lamps in a wide range of industrial processes.

- Example of Applications -

UV Fluorescence Detection of Conformal Coatings

UV fluorescence detection of conformal coatings is a quality control method widely used to verify the application of conformal coatings on electronic circuit boards and sensitive components. When exposed to ultraviolet light, fluorescent coatings become visible, making it possible to quickly identify covered areas, missed spots, or application defects. This non-destructive inspection technique improves the reliability of production quality checks and ensures accurate traceability of protective coating operations.

UV Inspection for Dust and Contaminant Detection

UV fluorescence inspection is a quality control method that enables the effective detection of dust, particles, and contaminants present on industrial, optical, or electronic surfaces. Thanks to ultraviolet illumination, residues that are normally invisible to the naked eye become clearly visible, allowing for precise inspection before assembly, packaging, or processing operations.

UV Detection and Anti-Counterfeiting Authentication Solutions

UV fluorescence is a control and security technology widely used to combat the counterfeiting of products, documents, and packaging. It relies on the use of fluorescent inks, invisible markings, and security features that become visible under ultraviolet light, enabling fast and reliable authenticity verification. This UV authentication method is particularly common in the luxury goods, pharmaceutical, secure document, and industrial sectors, where product traceability and integrity are essential.

Gemological Analysis and Gemstone Inspection Under UV Light

UV fluorescence in gemology is an analytical technique used to study all types of minerals by observing their reaction under ultraviolet light. It helps identify certain natural characteristics, detect potential treatments, and differentiate the various components of a sample. By providing additional information about the structure and origin of gemstones, UV fluorescence is an essential tool for improving authentication reliability and enhancing gemstone analysis.

Industrial Quality Control Based on UV Inspection and Fluorescence

UV fluorescence systems play a critical role in industrial quality control by enabling the rapid detection of defects, cracks, contamination, and anomalies that are difficult to identify under conventional lighting. Through ultraviolet inspection, verification processes become more accurate, reliable, and efficient, helping to improve product compliance and enhance maintenance procedures. This non-destructive inspection technology is particularly valued in the electronics, aerospace, medical, and industrial sectors, where high standards of quality and traceability are required.
