All About Coatings

By Edmund Optics
14 October 2014

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

By Prof W R. Browne, Dr A. Draksharapu, Stratingh Institute for Chemistry, NL & Dr E. Illy Cobolt AB
26 September 2014

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.

New compact high repetition rate lasers for LIBS

By Håkan Karlsson, Elizabeth Illy, Bertrand Noharet & Tania Irebo
3 June 2014

White Paper Lead ImageLaser-induced breakdown spectroscopy (LIBS) is an atomic-emission spectroscopy technique that enables rapid chemical analysis of a wide range of materials ranging from metals, semiconductors, glasses, biological tissues, plastics, soils, thin-paint coating, and electronic materials. The LIBS technology has received substantially increased interest over recent years as a result of the development of more compact, even hand-held, systems that enables in-field use and construction of tools for on-line material analysis. This development has been made possible by the increased availability of more compact and industrial-grade system components including lasers, spectrographs and CCD cameras. In this application note we present how a new class of compact lasers with multi-kHZ pulse repetition rates enables significant reduction of the footprint of a LIBS system.
