Correlating advanced 3D optical profiling surface measurements to traceable standards

Bruker Nano Surfaces and Metrology
22 Jun 2023

In this application note, Bruker Nano describes the advantages of the non-contact inspection method employed by 3D optical profilers, and discusses the best practices and measurement results for some specialized physikalish-technische bundesanstalt (PTB) traceable roughness standards and other low-cost fingernail roughness gages. The correlation results are based on measurement factors that should be understood and considered when imaging and analyzing surface textures that range in roughness from a few nanometers to micrometers in scale.

ProfilometersProfilometers are instruments used to measure a surface's profile, in order to quantify etch depth, deposited film thickness, and surface roughness. They operate in either contact or non-contact modes and may use optical or stylus techniques to make the actual measurements.Light MicroscopyLight microscopes or optical microscopes are used to visualize microscale objects under magnification, including cells, clinical specimens and materials. Lab equipment for light microscopy includes confocal microscopes, fluorescence microscopes, zoom and stereo microscopes. Microscope slides and imaging reagents are available for visualizing samples, as well as various microscope stages and incubators for large or temperature-sensitive samples.
