Application of Forensic Comparison Microscope in Firearms and Industry
Within reply to the multiple demands of forensic science and inspection microscopy for industrial quality control is the use forensic comparison microscope. Based on the inventive design by Albert S. Osborn, forensic comparison microscope enables the comparison of two specimens put together in a single field, viewed by a single 10x eyepiece.
The forensic comparison microscope is outfitted with two 48-millimeter 2x objectives, but higher power objectives, with magnifications ranging from 2.6 xs to 100 xs, are obtainable as optional accessories. By recognizing that forensic applications often demand low power, large field binocular microscopes, the forensic comparison microscope design engineers prepared their comparison microscope interchangeable with the KW binocular body and its paired eyepieces. Without having to move the specimen and reference materials or adjusting the illumination, the binocular body can be substituted for the forensic comparison microscope monocular body on the same strong black metal stand. The stereoscopic instrument provides three dimensional reliefs and reveals overwriting, patching, erasures, folds, and crossed lines with startling distinctness that complements details revealed under the forensic comparison microscope.
The firearms and tool marks segment is answerable for the comparison of firearms, casings, projectiles and other proof that may be associated through tool marks. Tool marks result whenever two items come into contact with sufficient force, such that one or both of the items bear markings resulting from the other item.
The most important technique utilized in firearms and tool marks section is microscopy. The forensic comparison microscope allows two items to be viewed simultaneously. Evidence projectiles, casings, and other items bearing tool marks are compared to known items in order to find out consistency or inconsistency, both in class characteristics and individual characteristics. In adding up, the firearms section maintains a database program.
The data base program is headed by the Bureau of Alcohol Tobacco and Firearms. This program is an accomplishment because firearms are often transported across state lines, after having been used to commit crimes. If a cartridge casing is located at a crime scene, it can be added to the database and searched against known casings, and casings from other crime scene. Still if the firearm used in the crime is located much later, or in another state, the firearm can be compared to the database. Even though the original cartridge casing must still be compared to the indexed firearm, the database has the ability to link serial shootings and cold cases that or else would have no leads.
The firearms tool marks section of the laboratory was recently relocated to one place crime Laboratory. This move will allow the firearms section to grow, and has provided the former laboratory with much needed space. Evidence can still be submitted at the Central Laboratory, as periodic transfer of evidence between laboratories will be preserve.
By means of forensic comparison, microscope in forensic science purpose include the examination of criminal evidence, such as fingerprints or bullets as well as signatures and other discrepancies associated with deception and forgeries. Financial, insurance, legal, and law enforcement technical experts in the early twentieth century, comparing substances, surfaces, or colors, often used the forensic comparison microscope. For dealers in antiquities and other collectibles, this microscope would prove very useful for look over disputed or suspected documents and verifying historical documents, paper currency, artwork, gems, jewelry, and finishes. The forensic comparison microscope is too well adapted for quality control in industries such as textiles, paper, and paints, and for color matching, especially when the sample and reference materials are relatively undersized.
