Modulation Transfer Function Measurement - MTF Measurement Systems

    

In the optics lenses manufacturing process, accurately measuring lens distortion is a delicate task. The way this degradation can be evaluated is through Modulation Transfer Function (MTF) Measurement. VISIONx INC. has produced a customized version of VisionGauge^® machine vision software to be used in a sophisticated modulation transfer function measurement machine.

These customized MTF measurement systems support simultaneous image acquisition from 9 cameras, multiple display modes between which the user can change "on-the-fly", automatic MTF measurement, automatic PASS / FAIL determination, as well as capabilities for accumulating production & inspection data.

Our systems come with VisionGauge® OnLine machine vision software which contains an advanced and highly accurate measurement toolset. With resolutions up to 0.1 micron (um), these measurement tools provide accurate results every time.

These tools allow you to perform the numerous types of measurements, including:

• Point-to-Point Distance
• Horizontal Distance
• Vertical Distance
• Trace Width (arbitrary orientation)
• Point-Based Radius or Diameter
• Angle (4-point)
• Marker-to-Marker measurements, including fixed positions, intersection of two lines, center of circle, light-to-dark and dark-to-light edges, measurements between datums, etc...
• and more

Our VisionGauge® software is proven effective and accurate for Modulation Transfer Function (MTF) Measurement. Contact us for more information on how our machine vision systems can provide you with the results you need.

Information is also available about more recent applications solved with our fleet of VisionGauge® Digital Optical Comparators.
