Highlights
Built for the production floor.
- 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
