  • Patent number: 10228551
    Abstract: A chromatic confocal measuring device includes a light source, which emits light of a plurality of wavelengths, and a first beam splitter, via which the light from the light source into an imaging optical unit having chromatic aberration on. Light reflected from the measurement object is imaged by the imaging optical unit and the first beam splitter onto a first confocal detection stop arrangement, such that the first confocal detection stop arrangement functions as a confocal aperture. Light incident through the first detection stop arrangement is detected and evaluated by a first detection device. The measuring device has a first slit stop, which functions as a confocal aperture of the measuring device. The measuring device additionally includes a second detection device and a second beam splitter, wherein the second beam splitter splits the light reflected from the measurement object into a first and a second partial beam, which image the same spatial region of the measurement object.

  • Patent number: 7460289
    Abstract: The invention concerns an electrochromic device comprising a single supporting substrate (1) on which are disposed a working electrode (6) which is electrochromic per se and/or bears an electrochromic material on at least a portion thereof; a counter electrode (3); and a layer of an electrically insulating material (4) separating the electrodes; wherein said electrochromic material has a major surface at least a portion of which forms at least a portion of an external surface of the device. The new device allows deposition of electrochromic coatings on a variety of substrates which need not be transparent.

  • Patent number: 7403319
    Abstract: An electrochromic device in which specific channel direction for the conduction of ions is implemented. As a result ionic crosstalk between display pixels is greatly reduced and unwanted transient coloration effects are minimized. Further, specific gel, polymer, or ionic liquid solutions can greatly eliminate the corrosive effects associated with the use of electrolyte salt solutions.

  • Patent number: 7270880
    Abstract: The invention concerns discrete electrochromic particles comprising conducting, semiconducting or insulating nanoparticles having one or more electrochromic compounds adsorbed on the surface thereof. These particles may be deposited on an electrode in a single process step at a relatively low temperature, thereby allowing the use of heat-sensitive materials such as plastics as flexible substrates for the electrode.
