Optical Sensor for Non-contact Inline Layer Thickness Measurement of Thin Film and Coating

Coatings are becoming progressively thinner owing to the high prices of raw materials. The extremely thin layers (e.g. adhesive layers), generally measuring less than 1 µm, then have to be applied very homogeneously and in exactly the right thickness. The substrate material can range from highly transparent (e.g. glass) to highly reflective (e.g. aluminium).

Mounted on a traverse in a production environment, a StraDex t sensor is able to measure both wet and dry layers. The sensor can also be placed in a specially designed housing for applications in explosion protected areas. Two-dimensional offline studies of a coated material are feasible with this sensor installed in a SemDex inspection system.


  • Thin coatings > 0.3 µm (polymers) (adhesives, coatings, thin coats of paint)

  • Thin films < 15 µm


  • Non-contact measurement

  • Layer thickness range: 0.3 – 15 µm

  • Fast and robust measurement; repetition rate 4 kHz

  • Repeatabilities: down to 1 nm

  • Universally applicable with min. working distance of 10 mm; focussing over a height of 5 mm

  • Highly compact design

  • User-friendly StratoSpect software .
