The Role of Forensic Flashlights in Crime Scene Investigation (CSI)
Posted by Raymond on 7th Mar 2025
In crime scene investigations (CSI), forensic flashlights are vital tools that help uncover evidence invisible to the naked eye. These flashlights use specialized wavelengths to detect bodily fluids, trace evidence, and even authenticate documents. This article explores how forensic flashlights enhance crime scene investigations, with a focus on the TANK007 CI02 Combo Forensic Flashlight Kit — a versatile tool designed for professionals.

1. Why Forensic Flashlights Are Essential in CSI
Forensic flashlights emit specific wavelengths of light (UV, IR, and blue light) that cause certain substances to fluoresce or absorb light differently. This is crucial for:
- Detecting biological evidence: Bodily fluids such as blood, semen, and saliva can fluoresce under UV or blue light.
- Revealing fingerprints: Oils and residues in fingerprints react under specific wavelengths.
- Identifying fibers and trace evidence: Different materials absorb and reflect light uniquely.
- Authenticating documents: UV light can reveal security features in documents and currency.
2. Key Wavelengths Used in Forensic Flashlights
| Wavelength (nm) | Light Type | Applications in CSI |
|---|---|---|
| 365-395 | Ultraviolet (UV) | Detecting bodily fluids, fibers, and document authentication |
| 450-470 | Blue Light | Locating biological stains and enhancing contrast for fingerprints |
| 620-650 | Red Light | Enhancing bloodstains on dark surfaces |
| 850+ | Infrared (IR) | Document examination and detecting alterations |
TANK007 CI02 Combo covers a broad range of these wavelengths, making it a comprehensive tool for CSI professionals.
3. TANK007 CI02 Combo vs. Competitors
