Fluorescence Imaging
How QLF works, how it complements radiographs, the evidence behind it and the Qray lineup.

The four Qray devices share one principle — 405 nm fluorescence — but sit at different points in the workflow: Qraycam Pro for full-arch screening, Qraypen C for a close look at one tooth, Qrayview Pro to confirm biofilm removal, and Qscan Plus for home care between visits.

Quantitative Light-Induced Fluorescence: What 405 nm Shows
Quantitative light-induced fluorescence (QLF) uses 405 nm light to show two signals: green fluorescence from sound enamel and red fluorescence from bacterial porphyrins in biofilm that has matured for three days or more. QLF adds functional information to radiographs rather than replacing them.
