The comparison microscope is used in forensic sciences to compare microscopic patterns and identify or deny their common origin. These samples are prepared on slides and inserted; then, with the aid of a dichromatic mirror, the device produces a magnified image on a computer screen. Click card to see definition . That is, light is reflected from the object before entering the lens. The microscope also has a characteristic feature of photography to record and examine the samples for a detailed examination. It is also known as a dissecting microscope. Brightfield Microscope list. Microscopes in forensic science help you to investigate the site of a crime and study the cause and time of death distinguish homicide from suicide, determine the type of weapon used, and establish the identity of the deceased identify fingerprints and footprints and get trace evidence such as hairs and fibers, DNA, or handwriting Since it uses light that naturally reflects from the specimen, it is helpful to examine solid or thick samples. Stereo Microscopes enable 3D viewing of specimens visible to the naked eye. A hanging stand with a large range, allows comfortable work with larger objects.
