Modulation Transfer Function (MTF) Measurement

In the optics lenses manufacturing process, the accurate measurement of lens distortion is a delicate process. 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.

This customized version of VisionGauge^® machine vision software supports simultaneous image acquisition from 9 black and white 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 embedded with VisionGauge® OnLine machine vision software that contains highly accurate measurement tools. With resolutions up to 0.1 micron (um), the 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...

Our VisionGauge software is proven to be the perfect one for Modulation Transfer Function MTF Measurement, contact us for more inforamtion on how our machhine vision systems can provide you with the results you need.
