Multi-Band Uniform Light Source
Model: HW-A6
Introduction:
Multi-Band Uniform Light Source is a basic light source that can
emit full spectrum white light, combined with a set of special
filters, to obtain multiple monochromatic radiation electric light
sources through the adjustment of the filters. The filter system is
a set of high-quality band-pass interference filters, and the
filtered multi-color light can conveniently search and inspect
on-site physical evidence, as well as provide photographic light
distribution.
The Multi-Band Uniform Light Source is a new type of courtroom
scientific light source developed and mainly used by criminal
investigation and judicial departments. It is suitable for
displaying fingerprints, blood stains, body fluids (semen, saliva,
vaginal secretions, urine traces, etc.), fibers, gunshot residues,
bite marks, hair, and trace traces in various criminal scenes.
As a photography light source, it can be used for various forms of
photography such as UV, visible and infrared reflection
photography, fluorescence photography, etc. Its infrared light band
output can also be used for document inspection. It is small in
size and light in weight, suitable for both laboratories and
criminal scenes, and is an ideal equipment for physical evidence
identification and criminal scene investigation.
Main Features:
1.Compact and portable, integrated with six bands.
2.The wavelength band is independent of the light, paired with
high-quality filters, with precise wavelength bands and good
biological detection results.
3.Blue and green light use 30 watt high-power LED beads, which have
stronger light efficiency and better detection results.
4.Equipped with white light polarization accessories, it can
achieve polarized light photography.
5.LED LCD display screen, with clear information on battery level,
frequency band, and gear strength at a glance.
6.Adopting Type-C fast charging technology, the charging time is
less than two hours, and there is no waiting anxiety.
Applicable scope:
1) Search for trace physical evidence such as fingerprints,
footprints, bloodstains, fibers, etc
2) Search for physical evidence such as shooting residues, blood,
semen, and human tissue fluids
3) Improving the effect of fingerprint photography treated with
fluorescent reagents
4) Light distribution for UV, fluorescence, and color separation
photography
