With a rubber object, like the cast rubber form of four pits in a metal surface pictured below, measurement is quick, easy and precise with 4D InSpec.

In the screen capture from the analysis software shown below, you can see that the field of view is large enough (either 7mm x7mm, or 15mm x 15mm, depending on your 4D InSpec model) to measure all four bumps in the rubber cast. The rough area around each pit, where the coating flaked off, is also characterized. At the left in green, is the false-color camera view, in the center in the green square with red and orange dots, is the peak to valley representation of the bumps. At the upper right, with the gray area representing undefined features, the four bumps are classified according to feature definitions in the Features Analysis functions of the 4D InSpec software. Since each of the four bumps fit into a separate “bucket” of the parameters, there are four colors of feature found.

App Note on Replica Measurements


Measurements of Various Defects and Their Replicas Using the 4D InSpec

This paper asks and answers the question, “Can direct, 3D, defect measurement mitigate the risks and limitations of replica materials?” through several approaches, sample measurements and tests.
