Thickness Measurements

optical thickness measurement µ-thick and mm-thick systems

Systems from Nirox srl, Brescia/Italy

how does it work?

• patented by Nirox srl, it represents the latest measuring solution available on the market to optically measure thickness.

• the measure is based on the light reflected at entrance and exit interfaces (r1 e r2).


hh

• optical head collect both reflections and make it possible to obtain interference between them.

• the resulting optical signal intensity has a component directly related to the physical thickness d and the index of refraction n of the material.

Applications

• Materials measured : any transparent or semitransparent material (colours and/or particular surface finish need specific testing); coating on substrates.

• What is measured : total thickness of a single or multi layer structure; thickness of a single layer coated on glass/metal. Layer discrimination of sandwich structure is under development.

Target markets

  • Plastic material extrusion
  • glass production lines (flat, hollow)
  • Coating on glass or metal substrates
  • Medical plastic devices
  • Coating on optical devices
  • Semiconductors, photo resist and oxides

Main Advantages

  • one-sided measure (reflection)
  • high accuracy
  • non-contact, non destructive measurement
  • light used is not dangerous
  • easy to use
  • quick integration in laboratory and production lines.

Medical tube

• delivery of MI measuring equipment with multiple optical heads layout (wall-thickness and concentricity)

• delivery of supervisor system (panel-pc) with real-time trend charts and SPC data (statistical process control)
thickness measurement

System options

• distributed optical heads: a single measuring unit with an optical switch can drive several optical heads for distributed measurements

• supervisor software : real-time data display and production data management

• laboratory scanner: delivery of stand-alone unit with motorized x-y positioning system for measurement of thickness profile (1D) or maps (2D)

• custom software: software customization for specific needs
