Getting the most from a 4D InSpec.
Application Notes
In the App Notes offered here, our experts research customer questions, and explain properties of measurements by 4D InSpec. They provide instructions on how to make a better measurement, and explain complex metrology issues, because we believe better understanding makes a better world.

Learning How to Measure [Better]
Gage-Capable Feature and Defect Measurement with a 4D InSpec® Surface Gage
This 4D InSpec application note presents a pair of repeatability and reproducibility studies: one on scratches and dents, and another on edge break chamfers.
SPOILER: 4D InSpec is more repeatable than other solutions.
Take a 3D Measurement and Then Compare the Result to a CAD model
This 4D InSpec application note shows a simple example of exporting a 3D measurement from 4D InSpec as .XYZ, then importing that and the CAD file for the part surface in a third-party software package, comparing the measured part to the designed CAD model.
Measuring Transparent, Flat or Shiny Surfaces with the 4D InSpec
Transparent materials are measurable by the 4D InSpec, albeit with some limitations. This paper discusses how to measure defects on transparent material, and how a replica material to measure feature depths on transparent surfaces.
Measurements of Various Defects and Their Replicas Using 4D InSpec
This paper looks at how to use 4D InSpec with replica pastes and gels. It answers the questions of whether 4D InSpec measurements of parts and measurements of replicas correlate. And it advises when to use a replica, and when to just go ahead and make the measurement directly.
Measuring Highly Reflective Curved Surfaces with the 4D InSpec
Curved, shiny or smooth surfaces can be challenging to measure. The curves create highlights that can saturate the imaging sensor, making areas of missing data. This app note explains why this is, and how to adjust your measurement technique to get the data you need.
Step Limitations of Fringe-Based Measurement Systems
People often ask us why there’s a step limitation with 4D InSpec. It’s because the gauge uses a method of calculating heights that’s like the topographical lines on a map.
In this app note, we explain how come fringe-based measurement systems can only handle steps of limited heights.
