Ultra-Wide Spectrum Forensic Camera

Ultra-wide spectrum forensic cameras capture evidence images across ultraviolet, visible, and near-infrared wavelength bands from a single instrument, giving forensic examiners a complete multi-spectral photographic record of physical evidence without switching between separate camera systems for each illumination type. Police forensic units, criminal investigation departments, forensic science laboratories, and judicial expert witness programs across Pakistan use these cameras to document latent fingerprints, biological stains, document alterations, and trace material deposits at crime scenes and laboratory examination benches.

The camera sensor uses a high-resolution CMOS or CCD array with spectral sensitivity extending from 200nm ultraviolet through 1000nm near-infrared without the infrared cut filter found in standard consumer cameras. This full spectral sensitivity allows the camera to capture images under UV, visible, and NIR illumination sources using the same sensor and lens without hardware changes between spectral band captures. Image resolution runs between 20 and 50 megapixels. This delivers sufficient detail for fingerprint ridge comparison, document fiber examination, and trace evidence documentation at forensic exhibit scale. Additionally, bandpass filter sets in 365nm, 450nm, 530nm, 590nm, 630nm, 850nm, and 940nm mount on the lens via a filter wheel or manual swap, isolating specific spectral bands for targeted evidence visualization during the examination session.

UV fluorescence photography uses 365nm excitation illumination with a barrier filter on the camera lens blocking reflected UV while passing longer wavelength fluorescent emission from latent fingerprints, biological stains, and document security features. This technique reveals evidence invisible under white light without contact or chemical treatment of the evidence surface. Furthermore, NIR reflectance imaging at 850nm and 940nm penetrates surface inks and coatings on questioned documents, revealing obliterated writing, ink substitutions, and altered entries where underlying content differs in infrared reflectance from the overlying surface modification.

Tethered operation connects the camera to a forensic workstation through USB or Ethernet. Dedicated forensic imaging software controls capture parameters and stores images with chain-of-custody metadata for each examination session. Moreover, lightweight body construction runs between 800 grams and 1.5 kilograms including lens, supporting both bench examination and crime scene field documentation use across forensic investigation programs throughout Pakistan.

Tactical Supply Pakistan supplies ultra-wide spectrum forensic cameras to police forensic science units, criminal investigation departments, forensic science laboratories, and judicial expert witness programs requiring multi-spectral evidence photography capability across crime scene and laboratory forensic examination applications throughout Pakistan.
