The Electron Microscope is an advanced type of microscope that uses a beam of accelerated electrons to magnify objects to a much greater extent than is possible with light microscopes. Hans Busch developed the first electromagnetic lens in 1926. Here’s an overview of its principle, instrumentation, functional mechanism, and forensic […]

Comparison Microscopy stands as a cornerstone technique in forensic science, facilitating meticulous examinations and comparisons of physical evidence critical to criminal investigations. This sophisticated method involves the simultaneous observation of two specimens under identical conditions, offering a side-by-side analysis essential for identifying similarities or discrepancies between them. Whether examining toolmarks, […]
Fluorescent Microscopy has emerged as a transformative tool in various scientific disciplines, offering unparalleled capabilities for visualizing and analyzing a wide range of biological, chemical, and materials samples. Unlike conventional light microscopy, which relies solely on transmitted or reflected light, fluorescent microscopy harnesses the unique properties of fluorescent molecules to […]
The Stereo Microscope, also known as a dissecting microscope, is a type of optical microscope designed for low-magnification observation of three-dimensional objects. Here’s an overview of its principle, instrumentation, functional mechanism, and forensic importance: Principle The stereo microscope provides a three-dimensional view of specimens by using two separate optical paths […]
A Polarizing Microscope is an optical instrument used to observe and analyze materials under polarized light. It employs polarized light, which has its electric field oscillating in a specific orientation, to reveal the optical properties of specimens. The microscope consists of specialized components, including a polarizer, analyzer, objective lenses, and […]
A Compound Microscope is an optical instrument used to magnify small objects that are not visible to the naked eye. It consists of two or more convex lenses arranged in a series, which magnify the object placed on the stage beneath the lenses. Light passes through the specimen, is refracted […]
