The XY-100 UV/IR Lens is a highly integrated, modular handheld multi-spectral on-site evidence collection device, constituting core portable optical evidence collection equipment in the fields of criminal technical scene investigation, laboratory evidence preliminary examination, and judicial forensic multi-spectral imaging. Its core design concept integrates a specific-band light source, a high-transmittance optical lens, and a portable power supply into one unit, forming an independent, complete imaging unit. Without relying on external bulky independent light sources or complex filter systems, it can be directly adapted to most standard DSLR camera bodies, instantly transforming a conventional digital camera into professional ultraviolet, infrared, and multi-band fluorescence photography equipment. It greatly simplifies the operational procedure and enhances on-site response speed, making it an ideal crime scene evidence collection device for the rapid search, discovery, and documentation of latent traces.

Technical Principle

This lens operates on the synergistic principles of super-achromatic optical design and multi-band LED integrated illumination technology. At the optical level, the lens employs a super-achromatic design, precisely correcting the focal planes of the ultraviolet, visible, and near-infrared bands to the same plane through a combination of special optical glasses, ensuring clear imaging across the wide spectral range of 200nm to 1000nm. At the light source level, a multi-band LED light source module is built into the ring at the front of the lens, allowing for rapid switching between different output bands via a rotating dimmer knob. The entire system is powered by a built-in rechargeable battery, requiring no external power cables or independent light source heads.

Core Functions and Compliance Operational Value

Integrated Design and Instant-On Operation, Greatly Simplifying On-Site Multi-Spectral Examination Procedures

The device's original three-in-one design integrates the lens, light source, and battery, simplifying professional multi-spectral photography technology into an integrated lens that can be directly mounted on a camera. Investigators can immediately begin searching and photographing upon powering on and rotating the dimmer knob to the corresponding band, significantly enhancing the response speed and coverage of criminal technical scene investigations.

Multi-Band Switchable Light Source and Wide-Spectrum Imaging, Meeting the Full Range of Trace Detection Needs

The lens features built-in multi-band LED light sources. In blue light mode, it can effectively excite the fluorescence of body fluid stains, fibers, and fluorescently treated fingerprints. In violet light mode, it can create high-contrast bloodstain images on dark or complex backgrounds. In red and infrared light modes, it can penetrate certain inks or filter out background interference for document examination.

Super-Achromatic Optical Design and 1:2 Macro Capability, Ensuring Wide-Spectrum Imaging Clarity and Fine Photography of Minute Traces

The lens employs a super-achromatic optical design, requiring no repeated focusing when switching between bands. It also possesses an excellent 1:2 macro close-up capability, allowing for the direct photography of minute trace details such as fingerprints without the need for additional close-up lenses.

Compliant Application Scenarios

Rapid Search Scenario for Biological Stains and Trace Evidence at Homicide and Assault Crime Scenes

At crime scenes, investigators use this lens in blue light mode to scan areas such as bedding, clothing, and walls. The blue light can excite body fluids such as seminal, saliva, and urine stains to produce characteristic fluorescence, providing precise localization guidance for subsequent DNA extraction.

Rapid Detection and Preservation of Latent Fingerprints and Footwear Impressions at Burglary Scenes

At burglary scenes, investigators use this lens to illuminate smooth, non-porous surfaces. Under blue light, latent sweat fingerprints may produce direct reflection contrast or faint fluorescence, facilitating rapid detection and photographic documentation.

Rapid Preliminary Examination and Security Feature Identification in Document Examination

In cases involving document fraud, examiners use this lens to perform infrared reflection photography on suspicious documents in infrared light mode, revealing obliterated writing. In blue or violet light modes, UV fluorescent security features on passports, banknotes, and negotiable instruments can be rapidly identified.

Core Technical Parameters

The spectral imaging range ensures clear imaging across the wide spectral range of 200nm to 1000nm. The lens is available in 52mm and 58mm diameters, adaptable to most camera brands. The UV lens elements are manufactured from high-quality quartz glass. The macro magnification ratio reaches 1:2. The light source module supports switching between white light, blue light, violet/near-UV light, red light, and infrared light. The built-in rechargeable battery supports prolonged on-site operation.

Compliant Field Application Cases

While investigating a residential burglary, investigators from a municipal public security organ discovered multiple suspected fingerprint marks on the glass pane of a window the suspect had pried open to enter. Due to strong reflections and a complex background on the glass surface, the fingerprint ridges could not be clearly visualized under conventional white light illumination. Technicians used this XY-100 UV/IR Lens, switching to blue light mode to illuminate the suspicious area, and clearly observed fluorescence images of several latent sweat fingerprints in the camera viewfinder. The technicians then performed scaled photographic documentation. The resulting fingerprint images exhibited clear ridges and, after being entered into an Automated Fingerprint Identification System for comparison, successfully matched a suspect.
