  • Visualization of all types of anti-Stokes
  • Red, green and blue luminescence
  • Protective Filter and safe design

Portable device Devis -Visan allows control security features based on anti-Stokes luminescence. For efficiency labels in the anti-Stokes imaging device used a special laser that provides enhanced anti-Stokes field illumination tags, as well as implemented a shaded area of observation. Security expert from the action of powerful laser radiation invisible achieved a set of measures: from the eyepiece - using a special filter in the observation by the working surface of the device - using two position sensors, switching off the laser device in the separation of the test surface.
