  • Crane & Co. Receives Exclusive Rights to Spectra Science's LaserPaint

Photonics Spectra
May 1997
Spectra Science Corp. has licensed LaserPaint, a covert coding and authentication technology, to Crane & Co. of Dalton, Mass., for use in Crane's next-generation currency and secure documents applications. The technology combines laser dyes and titanium oxide in a polymer host, enabling production of wavelength-tunable material that can form discrete codes when optically excited. (See "Photonics vs. Counterfeiters," Photonics Spectra, November 1996). The agreement gives Crane -- the sole US currency paper manufacturer since 1870 -- exclusive worldwide rights to the technology in exchange for license fees and royalty payments.
