Trace Evidence

Leeds

The Leeds’ Comparison Bridge is designed for forensics and other sciences where the comparison of specimens such as hair, fibers, surfaces or cross sections of paint layers, plant parts and dust or dirt particles, is done under the compound microscope.

With the LCT Trace Evidence Comparison Microscope, two specimens can be viewed as: split-field, superimposed or right/left field individually. Separate slide controls allow for continuous adjustment from 100% of the left image to 100% of the right image, or any position in between. A detent locates the center split position on the right image. The center split position for left image is user adjusted so that the dividing line width can be varied as desired.

The high quality optical system provides superior color balance with no adjustment needed by operator. A large 22mm field of view and an erect unreversed image, moves in the same direction as the object for quick easy manipulation of the specimen.

The LCT Comparison Bridge has a superior color and light intensity balance which makes it possible to use a single light source and a randomized, calibrated, bifurcated fiber-optic light guide to provide consistent illumination to both the right and left images.

The modular design makes it possible for transmitted and/or reflected light configurations to allow for universal applications with Olympus BX microscope components. The bridge can be used for brightfield, darkfield, polarized light, phase contrast, fluorescence and other contrast methods.

Comparison Bridge with dual-viewing option

A dual-viewing accessory can be added for simultaneous observation of evidence for training and consultation. An illuminated LED arrow aids in indicating a point of the specimen.

The compact footprint takes up minimal work space. One person can easily operate both microscopes and it is also capable of single microscope use applications such as investigation of biological, medical or chemical specimens in all types of illumination.
