​​Lepton-id Inc.

We offer many forms of taggants: Chemical,  Physical, RFID and Software


A taggant is also a chemical or physical marker added to materials to allow various forms of testing.  A physical marker taggant consisting of microscopic particles. It is a  secretive process.  A large list of products that may be secured include ink, paper, perfume, medication etc.. Taggants allow testing marked items for qualities such as lot number and concentration (to test for dilution, for example). Taggants are  widely used in plastic, ink, sheet and flexible explosives.


RFID, as a tagging, is a radio frequency microchip used in automated identification and data capture.  Electronic devices that use radio waves to track and identify items, such as pharmaceutical products, by assigning individual serial numbers to the containers holding each product.

software taggant is a cryptographic signature added to software that enables positive origin identification and integrity of programs. 


​We have numerous patents filed and granted.

Lepton-id Taggant

At Lepton-id, we offer many different taggant anti-counterfeit solutions currently in 7 versions.  Within each version, we offer custom solutions or derivatives to service your specific requisite.  From taggants, to delivery mechanism, to forensic patterns, to detectors, we are a one stop shop for your anti-counterfeit up conversion or down conversion product solutions.

UV to IR
We use down conversion techniques (Stokes) to transmit a material that absorbs energy at a short UV wavelength to emit energy at a longer visible wavelength.

Visible to IR
We use down conversion techniques (Stokes) to transmit a material that absorbs energy at a shorter visible wavelength  to emit energy at a longer IR wavelength.

IR to IR
We use down conversion techniques (Stokes) to transmit a material that absorbs energy at a shorter IR wavelength to emit energy at a longer IR wavelength.

IR to Visible
We use up conversion techniques (Anti-Stokes) to transmit a material that absorbs energy at a longer IR wavelength to emit energy at a shorter visible wavelength.

NIR  to SWIR
We use down conversion techniques (Stokes) to transmit a material that absorbs energy at a shorter IR wavelength to emit energy at a much longer SWIR wavelength..
 
UV to Visible
We use down conversion techniques (Stokes) to transmit a material that absorbs energy at a shorter wavelength (UV) to emit energy at a slightly longer wavelength (Visible).

Multi-spectrum taggants
Some material may have both Stokes and Anti-Stokes characteristics in which the absorption and emission spectra can cover a range from UV to NIR. The spectra of the material may or may not have optical characteristics that overlap. This allows us to configure a unique material.
