The small size of the fibre, combined with the variety of fluorescent colours in precise register, makes it difficult to counterfeit.
Four-colour Rainbow Fibres™ are completely invisible in normal light but under ultra-violet light, they fluoresce in four different colours along the length of the fibre. We can combine dual-fluorescence, so that colours are different under long-wave and short-wave fluorescence
The ‘rainbow’ appearance of the fibres makes it easy to describe and easy for the observer to identify, making this a semi-public security feature if an invisible feature is combined with a visible feature.
Add a 2nd level with different colours under short wave U.V. light.
Add a 3rd level with a machine-readable or IR absorbing feature.
Choose from any of the options below to create a truly unique fibre.
