Stepless Dimming
Brightness can be adjusted continuously to support trace detection in different scenarios.
Portable Battery System
Built-in 12,000 mAh battery and 24,000 mAh external battery pack support field use.
Field Applications
Crime Scene Search
For searching footprints, impression marks, bloodstains, fibers, and other trace evidence.
Traffic Accident Investigation
Can be used for tire mark inspection at traffic accident scenes.
Illumination and Control Design
Light Output
The light source uses pure white light with a 400–700 nm spectral range and adjustable 4000K–5700K color temperature.
The output width is 152 mm, with an 80° horizontal angle and a 15° vertical angle.
Optics and Control
The device uses optical quartz glass lenses and 16 high-power LEDs for uniform and stable illumination.
It also includes stepless dimming, automatic temperature protection, low battery warning, and a filter slot for interchangeable wavelength filters.
Application Results
Trace Mark Visualization
Adjustable illumination helps make surface traces easier to observe.
Enhanced Contrast
Interchangeable filters can help increase contrast on complex backgrounds.
