LS-VNIR-FS Portable Hyperspectral Evidence Analyzer

LS-VNIR-FS Portable Hyperspectral Evidence Analyzer

The LS-VNIR-FS Portable Hyperspectral Evidence Analyzer uses line scanning pixel-coated hyperspectral photosensitive elements for gaze photography across a 470-900nm working range. It collects continuous hyperspectral data from 150 spectral bands and generates standard reflectance data through an included reflectance calibration plate. The unit features a built-in scanning hyperspectral imaging instrument with integrated modules for imaging, signal processing, mechanical control, power management, and temperature regulation.

This compact system requires no external power supply or complex push scanning platforms. It operates through a single USB Type-C data cable that handles power supply, device control, and data transmission simultaneously. The analyzer produces target object reflectance spectral curves from 150 bands with single fiber output achieving optical path loss under 1%. It offers uniform light output with adjustable light spots suitable for various environmental evidence detection requirements.

Forensic laboratories deploy the LS-VNIR-FS Hyperspectral Evidence Analyzer for trace evidence examination including fiber analysis, ink differentiation, and biological fluid detection on questioned documents and physical evidence. Crime scene technicians use this system at investigation sites requiring immediate spectral analysis of stains, residues, and material compositions without transporting evidence. The technology enables users to establish custom feature spectral library files for comparison against collected evidence samples.

Tactical Supply Pakistan provides this laboratory and field-deployable hyperspectral analysis system to forensic units requiring rapid spectral characterization capabilities without stationary laboratory infrastructure dependencies. The portable design supports quick deployment across multiple examination locations.

Why does hyperspectral analysis reveal evidence invisible under standard lighting?
Materials absorb and reflect specific wavelengths across the 470-900nm spectrum based on molecular composition—blood, semen, and chemical residues exhibit unique spectral signatures that the 150-band system detects even when visually indistinguishable from backgrounds under white light illumination.
