UV Fluorescence Simulator

A common method for detecting modern forgeries on vintage items is UV fluorescence. This tool simulates the reaction of different paper eras to 365nm UV light.

Fact: Modern paper (post-1950s) contains optical brightening agents (OBAs) that fluoresce bright blue/white under UV light. Pre-1950s paper appears dull yellow/brown. If a "1920s" document glows bright blue under UV, it is definitively forged.

Diagnostic Note

Optical Brightening Agents (OBAs) were introduced in the paper manufacturing process in the mid-20th century to make paper appear "whiter". Under 365nm UV light, these chemicals fluoresce intensely.
