Spirit Sampling for Counterfeit Detection and Brand Authentication

By Nick Barnett. Ph.D
7 November 2014

White Paper Lead ImageIncidents of whisky and spirits counterfeiting pose serious health risks to citizens and potential revenue loss to brand owners. The Ocean Optics Spirit Sampler can help to combat increased sales of illicit spirits by providing a means of counterfeit detection and brand authentication in the field. The success of such a screening device depends on the reproducibility of measurements from sample to sample and from device to device. This application note describes measurements performed to demonstrate Spirit Sampler device reproducibility and outlines some of the instrument’s brand management software features.

How is laser Power/Energy measurement affected by incidence angle?

29 October 2014

White Paper Lead ImageModern laser applications demand ever-increasing accuracy in the measurement and control of the laser beam. Various types of sensors and instruments are in use today, the choice depending on the type of measurement needed. However, even given the correct choice of equipment, there are measurement conditions that can seriously affect the accuracy of the readings obtained if not correctly taken into account.

All About Coatings

White Paper Lead ImageIn every realm of physical science, surface properties dictate much of the interaction between an object and its environment. This is true for optics as well. Although the bulk properties of glasses certainly influence an optic’s interaction with light, the shape and smoothness of the surface are the primary determinants of the way a lens or mirror modifies the propagation of light. In addition to surface shape and quality, the coatings on an optical surface strongly affect an optic’s interaction with light. Specifically, coatings significantly modify the behavior of light at different wavelengths. Nearly every modern optical system depends on effective optical coatings.

Using the full spectrum for Raman: from UV to NIR

White Paper Lead ImageThe ”inelastic scattering of light”, or Raman effect, was observed in practice for the first time in 1928 by C.V. Raman for which he was awarded the Nobel Prize in 1930. It is only in the last two decades, however, that Raman spectroscopy has begun to realize its potential as an almost universally applicable analytical technique from materials and life sciences applications to point of care analysis. This is primarily thanks to the availability of compact laser sources, high sensitivity cameras and high resolution compact spectrometers.

Technology Features

Electro Optics coverPhotonc sensor to combat TB

A lab-on-chip device, being designed as part of a European project, promises to reduce the cost of diagnosis tuberculosis dramatically – and save many lives in the developing world. Greg Blackman speaks to Wim Van Roy at Imec, one of the coordinators of the project
