NON-CONTACT

CENTER THICKNESS MEASURING SYSTEM


  • highly precise and easy to use non-contact system for measuring the thickness of optical elements in both, production and quality inspection environments


  • integrated interferometric sensor for fast, reliable and high precision thickness measurement


  • measurement of single elements and doublets


  • lenses automatically centered with an innovative precision 3-jaw chuck system


  • measurement of elements with one side access only is accommodated. Ideal for testing lenses - even mounted to holders - with demanding CT tolerances in the polishing operation


  • measurements of elements with one side access only is accommodated. Ideal for testing lenses - even mounted to holders - with demanding CT tolerances in the polishing operation


  • measurement of SAG depth, surface aperture diameter, total lens height and stock removal are supported in addition to CT measurement


  • ergonomically positioned lens holder provides for safe easy and fast loading and setup of workpieces up to Ø200mm


  • extensive integrated glass database provides ready access to index data. Software supported index finding device allows for easy and quick automatic analysis of unknown index values


  • easy and touch screen optimized dialouge user interface 
  • automatic counting / numbering of lenses 
  • green (in spec) or red (out of spec) display of measurements
  • data input manually or via OR code reader 
  • zoomable live display of measurement signal
  • live feedback for correct positioning of the substrate
  • adjustable threshold for signal processing
  • measurement result within in less than 1 second
  • index finding tool for precise measurment of the materials index
  • integreated database with indexes of most material suppliers
  • possibility of creating own database with self measured indexes
  • revers calculation of material index to confirm correct material
  • single lenses and flats
  • various UV // VIS // IR materials
  • lenses on holders and chucks
  • protection painted lenses
  • Doublets,Triplets, Sub-Assemblies
  • Air gaps and Sagital depth
