How to Select the Right Measurement Microscope

This article has the following contents:

• Why use a measurement microscope?
  Measurement microscopes are essential tools for analyzing the dimensions of sample features and are crucial for inspection, quality control (QC), failure analysis, and research and development (R&D).
   
• How to select a measurement microscope
  Choosing the right measurement microscope for your needs depends on the:
  • Sample type, size, and its features of interest
     
  • Application, for example, whether inspection QC, failure analysis, or R&D
     
  • Performance of the microscope which determines how clearly it can resolve fine details and accurately measure sample features
     
  • Resolution of the microscope, i.e., it's ability to distinguish fine details
     
  • Camera’s pixel size which is important for resolving sample features viewed or measured on a monitor
     
  • Optical quality and correction of the microscope optics for chromatic or spherical aberrations and flatness or planarity which can affect measurement accuracy by causing significant distortions of the image.
     
• Choosing the right kind of microscope
  Whether using a stereo or compound microscope with a digital camera installed or a digital microscope, there are important factors to consider when determining the appropriate type of microscope to use for measurement.
   
• Examples of measurement microscopes
  For basic 2D measurements (refer to example shown below), advanced 3D measurements, and automated measurements, examples are given.
