Characteristics of forensic microscopes
Forensic microscopes are special optical devices used to analyze, compare two samples. They are used in the identification of drawings, casings, handwritings, seals, locks, fingerprints.
According to the results obtained, the experts give a conclusion, which plays an important role in solving the crime. Therefore, such equipment is of high quality and accuracy.
Arstek can order microscopes and the accompanying accessories that will help you in solving any problems. The catalog contains laboratory devices that are suitable for examining various materials, determining similarities and differences in paired samples.
Equipment characteristics
These microscopes have a dual design, consisting of a pair of identical objectives with a common optomechanical module. This property is irreplaceable when analyzing fingerprints, comparing them with an archive or database.
The model consists of a tube and a beam splitter with two optical devices for viewing materials separately. The optical-mechanical module combines two images into a single space, which are viewed in parallel. Thanks to the dividing line, the pictures will not overlap. This feature allows you to perform the following work:
- Compare two objects in a common visual space.
- Analyze each sample at multiple magnification.
- Partially or completely overlap lenses.
- Contrast using polarization, ultraviolet waves, fluorescence, etc.
Samples with different parameters, shapes and shades are suitable for analysis. Special holders are used to attach objects or preparations to the stage.
Advantages of devices
Features of designs in forensic microscopes form the following advantages:
- The effectiveness of the analyzes. Detailed and numerical information eliminates errors that can occur when visually identifying samples.
- Efficiency of surveys. High-precision optics enable the equipment to generate a post-examination report.
- Multiplicity of magnification, innovative methods of illumination of the working field provide a thorough study of materials, the quality of examinations.
Using microscopes in comparison
The main field of application of the devices is comparative expertise in forensic traceology and ballistics. Documents, bullets, shells, hair, fingerprints, tissue fibers, small objects and particles are also examined.
The equipment allows to carry out:
- Observation, research of objects in various modes.
- Conduct contrast-enhanced analyzes.
- Receive images with increased color resolution.
The equipment is suitable for use in expert medical and forensic structures, government agencies, research institutes dealing with ballistics and traceology.
Comparative devices can be combined with digital video and photo cameras, computer programs for image analysis. The devices are almost 100% accurate, there is no risk of errors and inaccuracies.
The variety in the nature of the tasks performed leads to the need to develop several types of microscopes, to equip them with special devices to expand the field of research.
