OptiGauge in exclusive cooperation with
Lumetrics Inc.

OptiGauge Was Developed for Precise Measurement
of Multiple Materials

• Technology was originally created by Eastman
  Kodak for thin film measurement.
• How Does it Work?
• Infrared light is emitted from luminescent diode.
• Beam travels through all layers of material and
  is reflected back to optical sensor in the probe.
• Highly Accurate Results are generated in
  real-time.
• Layers are displayed in top to bottom order.

43
Plastic microstructure

• Measures all peaks and valleys
• Extremely accurate profile of total area
• Profile includes highs, lows and averages

44
How to Read The Screens

• Diagnostic Screen
• IR Light from the probe generates energy peaks
  from individual layers of film. The peaks are
  the separate surfaces (top surface, interior
  surfaces/interfaces, bottom surface) that make up
  the film.
• The distance between peaks represents thickness
  the red marker lines aid in identifying the
  middle of the curves.
• On the screen below, there are five surfaces (red
  lines) that comprise four separate layers of
  material.

45

• Surface Scan Screen
• Numerical readout of information, including
• Mean/min/max thicknesses
• Optical Thickness the thickness of the film as
  if it had a Refractive Index of 1.0 ? user needs
  to enter actual RI of the plastic for an accurate
  reading.
• Lumetrics uses RI setting of 1.5 for most plastic
  materials
• Refractive index of the material being measured
  (user entry)
• Max thickness ? individual layer thickness
• Total Material ? cumulative thickness of material
• From this information, it is relatively easy to
  see all layers being inspected plus the total
  thickness of the piece.

46

• Graphical readout mode shows all layers with
  thickness callouts.
