Surface Boundary Measurement Using 3D Profilometry

In profilometer studies where the interface of surface features, patterns, shapes etc., are being evaluated for orientation, it will be useful to quickly identify areas of interest over the entire profile of measurement. By segmenting a surface into significant areas the user can quickly evaluate boundaries, peaks, pits, areas, volumes and many others to understand their functional role in the entire surface profile under study.

Profilometer software for NDT surface roughness inspection

Novacam 3D Profilometer Software

The Novacam three dimensional software programs are used with all Novacam Profliometers. The program permits the consumer to define how big the region, or line to be measured, along with the lateral resolution from the measurement.

Novacam's high end Data Acquisition Profilometer Software programs are incorporated with all of MicroCam non-contact profilometers.

Profilometers using Low Coherence Interferometry used by NASA to measures thickness

Using a fiber-based optical profilometer NASA measures the thickness of liquid nitrogen in cryogenic chambers at its Propulsion Systems lab because these profilometers use fiber-based probes which can withstands the extreme environment, can be located hundreds of meters away from the interferometer and fit in the tight chamber which standard full-field profilometers with a human operator could not. The signal quality stays constant over the distance.

Fractography Analysis Using 3D Profilometry

Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use.

Paper Roughness Measurement With 3D Profilometry

Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to measure paper surfaces.

Warpage Measurement of PCB With 3D Profilometry

Flatness measurement of electronic parts and assemblies, or PCB’s, has become increasingly critical as geometries become smaller: finer pitches, smaller solder ball volumes, thinner substrates, etc. Additionally, processing temperatures vary and can play a major role in PCB warpage and or planarity defects.

Surface Finish of Plastic Tubing With 3D Profilometry

The appearance and performance of a plastic component is highly contributed to surface finish. Monitoring surface finish for the intended parameters is crucial to the success of a plastic component both molded and machined. Insuring surface finish allows for the vast uses of plastic components and the environments they are found, ranging from medical to consumer goods, to electronics and cosmetics. For every use of a plastic component a specific surface finish parameter can be set to control its appearance and performance during environmental conditions.

Fiberglass Roughness & Flatness With 3D Profilometry

Although there are many uses for Fiberglass reinforcement, in most applications it is crucial that they are as strong as possible. Fiberglass composites have one of the highest strength to weight ratios available and in some cases, pound for pound it is stronger than steel. It is also important to have as little of exposed surface area as possible. Increased surface can make them more vulnerable to chemical attack and possibly material expansion.

Measurement of Cutting Tool Edge With 3D Metrology

For a particular tool, the edges precision is expected to meet intended results during use in machining. Because the depth of cut is controlled to the nanometer level, the tool cutting edge profile is an important factor to influence the final quality of a machined surface. By analysis of a 3D-Profilometer the edge correctness can be determined to insure quality control before production and or during the life of the tool.
