Process Summary:
A fluorescent dye-stain used to enhance cyanoacrylate-developed latent prints. A fluorescent light source that will output light between 415 nm and 535 nm is required for this process.
Accepted Deviations:
The wavelength at which fluorescence is optimized is adjusted in accordance to the personal preference of the examiner.
