Basic Microscopy

This course is part of the Basic Microbiology eLearning Series.


The microscope is an important diagnostic tool, used in laboratories, that allows you to view organisms too small to otherwise be seen. In order to accurately use the microscope, laboratory professionals must have a basic understanding of its parts and sections, care, maintenance, focus, and procedures for ensuring optimal illumination.

This basic-level eLearning course will review the correct use and maintenance of the brightfield microscope, including troubleshooting commonly encountered problems.


At the conclusion of this program, participants will be able to:

  • Identify the major components of the microscope and their function
  • Identify how to maintain a microscope
  • Discuss the role of Kohler illumination in microscopy
  • Describe the process to correctly focus on the appropriate field of view
  • Use the ocular micrometer to measure an object under the microscope
  • Demonstrate the ability to troubleshoot encountered problems with the microscope
