Trace Evidence

LCT comparison microscope 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. The bridge can be used for brightfield,
darkfield, polarized light, phase contrast, fluorescence and other
contrast methods.
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.
