Forensic comparison microscopy mostly needs a side by side comparison of the specimens. This kind of examination or test can be performed with forensic comparison microscopy. Mostly, the forensic comparison microscopy is two compound microscopes merged together to create a powerful forensic comparison microscope. The exceptional feature of forensic comparison microscopy design is that it uses a connection between the series of mirrors and lenses to connect two independent objective lenses into a single binocular forensic comparison microscopy. When the scientists, students, doctors look through the eyepiece lenses of the forensic comparison microscope, a circular field, evenly divided into two parts by a fine line, is seen. The specimen mounted under the left-handed objective is seen in the left half of the field, and the specimen under the right-hand objective is observed in the right half of the field. It is very important that the optical feature of the objective lenses be evenly matched to make sure that both specimens are seen at equal magnification and with lesser but identical lens alteration.
Modern firearm testing began with the introduction of forensic comparison microscope, with its capacity to give firearms examiner an accurate magnified view of bullets. Bullets are fired through the same rifle barrel will show similar rifling markers on their shells. By matching the common of striations present on each bullet, a conclusion that both bullets has gone through the same barrel is being proven. Read more on this subject
