Century of the Photon

The 1900s were the "century of the electron". Breakthroughs in electronics led the way to innovation and economic growth. The new century is being called the "century of the photon". The US National Photonics Initiative and Europe's Photonics21 provide needed infrastructure. ChromaID will become a new pillar for photonics.


Spectrophotometers

Spectrophotometers

Spectrophotometers combine broad-spectrum light; a diffraction grating to split it; and a Charge Coupled Device (CCD) for measurement. They tend to be bulky, fragile, and expensive; scanning and analysis are complex.

The Structured Light Breakthrough

Visualant is pioneering the use of structured light - a disruptive conceptual breakthrough in photonics. Light-emitting diodes (LEDs) each shine a single wavelength of light. Photodiodes measure the reflection for each wavelength.

ChromaID Sensors

ChromaID Sensors

ChromaID is the trade name for Visualant's implementation of structured light. LEDs and photodiodes make up a ChromaID sensor module, targeting pre-determined frequencies to generate a ChromaID Signature on the spot.

Extending the Promise of Sensors

Today's smartphones include cameras, gyros, accelerometers, proximity sensors, and fingerprint readers. Apps take your pulse with the camera and flash. A ChromaID module can easily be added to smartphone-sized devices. Extending the Promise of Sensors

The ChromaID Signature

When you scan a sample, you create a machine-readable tag: the ChromaID Signature. A quick database check yields a hit or a miss. Identification, authentication, and diagnosis are supported with each fast and easy scan.
