MEI610: FIBER IDENTIFICATION (FORMERLY COM402)
The Fiber Microscopy Course introduces the principles and practice of polarized light microscopy (PLM) to the identification of natural and man-made fibers. The course will be useful to anyone from a variety of sciences needing to identify fibers: pharmaceutical, textile, conservation, archaeological, and forensic. The students learn time honored and highly specialized PLM methods that can be successfully applied to virtually all types of fibers: vegetable, fur, mineral, and man-made. Allied topics that will be discussed include: fiber loss, shedding, and transfer; sampling and fiber recovery; contamination control; and handling microscopic size fiber fragments.
The student learning outcomes are achieved through lecture/demonstration and many practical exercises utilizing known and unknown fiber samples from a variety of industries. The outline below lists all of the major topics that will be presented during the course. John Delly’s new book “Essentials of Polarized Light Microscopy” will be a resource for continuing education in the field of Fiber Identification.

- Principles, theory, and practice of polarized-light microscopy (PLM) useful for fiber identification (using an Olympus BX51 microscope)
Everyone with the need for identifying fibers of all kinds, including:
- Chemists
- Materials scientists
- Textile scientists
- Archaeologists
- Criminalists
- Detailed course manual
- Essentials of Polarized Light Microscopy
- Olympus BX51 microscope with fluorescence capabilities
- "Understanding Textiles" by Billie J. Collier, Martin Bide, Phyllis G. Tortora
- INS500: Modern Polarized Light Microscopy
- Undergraduate science background
Students are expected to successfully complete a variety of tasks in the form of hands-on exercises, laboratory exercises, identifications of unknowns, and quizzes. In addition, the students are required to have 100% attendance during the course, participate in class, complete a student evaluation form and pre and post course assessment forms.
The student is notified at the end of the course whether or not they have successfully completed the requirements of the course based on:
- 100 % attendance
- class participation
- completion of all course material
- completed and signed student evaluation form
- completed pre and post course assessment forms.
Upon successfully meeting these requirements, a student is awarded a certificate of completion and IACET CEU credits, if available. Those who have not successfully passed the course requirements do not receive a certificate or IACET CEU credits.
