What you'll learn

  • Basics of microscopy
  • types of microscopes
  • significance of microscopy in forensics
  • applications of microscopes in forensics

Course content

3 sections • 9 lectures • 31m total length

  • Introduction7:06

    Explore the main microscopy types used in forensic microscopy—light, electron, and scanning probe—along with key concepts like magnification, resolution, and eyepiece.

  • Polarized light microscopy4:00

    Explore polarized light microscopy, using a polarizer and analyzer to reveal specimens with brightness at 45 degrees and extinction at 90 degrees. Apply to fiber, paint, and hair analysis.

  • Comparison Microscope2:45

    compare two bullets side by side using a comparison microscope, which links two microscopes with a bridge, enabling side-by-side analysis of bullets, cartridges, and striation marks, with digital image capture.

  • Stereomicroscope2:27

    Explore the stereoscopic dissecting microscope, an optical instrument for low magnification that yields a 3d image from surface light, using two optical parts and Greenough and CMO designs for applications.

  • Fluorescence Microscope3:20

    Explore fluorescence as emission of longer wavelengths after absorption, and learn how UV or xenon light, filters, and dichroic mirrors with fluorescent markers reveal cells.

Requirements

  • be able to understand English

Description

This course covers all the important aspects of forensic microscopy. Forensic microscopy is a field of microscopy which deals with application of microscopes for the purpose of examination of evidence helping in investigation. many crime scenes contain trace evidences which includes paint and glass fragments, drugs, tool marks, gun shot residues which can be visualized and analyzed with the help of microscope. Striation marks on bullet can also be compared and examined with the help of microscope which gives the examiner lead to the investigation. The techniques of microscopes cane be utilized effectively for solving the crime. Microscopes can also be used to study bone, tissues or other remains to find out the cause of death.

The lectures given in this course consists detailed instrumentation and working of each type of microscope. The diagrams are also incorporated in the lectures to make you understand the design and working of microscopes. This course consist of following topics-

  • Fundamentals of microscopy

  • Types of microscopes i.e., light microscopes and electron microscopes ( instrumentation, sample preparation, working) and its applications

  • Polarized light microscopy

  • Comparison Microscopes

  • Stereomicroscopes/ dissecting microscopes

  • Fluorescence Microscopes

  • Scanning Electron Microscopes

  • Transmission Electron Microscopes

  • Scanning Transmission Electron Microscopes

This course brings light to all the essential details of microscopes and how they are useful to examination of evidence in forensic science. At the end of this course, the students will be able to understand all the techniques of microscope and how to use it effectively for a particular type of evidence.

Who this course is for:

  • students who are curious to learn about microscopes
  • students who are interested in learning about the application of microscopes in forensic analysis
