Ellipsometry

Measurement of thin coating layers / residual dirt

cwgelli-1

So far, it has not been possible to measure thin coating and residual dirt with an online measuring process. These thin coatings have, until now, been unmeasurable.

cwgelli-2

Our newly developed optical measuring system, which works by the functional principle of ellipsometry, is able for the first time to determine coating thickness to 30 nanometres.

The science of measuring 1 litre of oil distributed over 30 soccer fields

Our newly developed optical measuring system, which works by the functional principle of ellipsometry, is, for the first time, able to determine coating thickness to 30 nanometres.

Tasks

Measure

either measurement of thin oil films on black plate

Recognise

Detection of residual oil/residual contamination in your skin pass rolling mills after annealing or cleaning processes

Record

Documentation of post-treatment layers in your finishing lines

Your challenges

  • Claims from your customers related to exceeded upper or lower limits of the organic coating layers, or due to uncoated areas

  • Offline-samples are not representative for the strip, too late intervention on failures

  • Missing quality verifications for your customers

Our solutions for you

  • Scanning Ellipsometer to measure organic coatings online

  • Online measurements feed-back of the measuring results to coating control systems

  • Recording of measuring results in customised quality reports
