Frequently Asked Questions

The OR-GJG4000 Forensic Laser System is used for the illumination and detection of forensic evidence in both field and laboratory settings. It reveals evidence through fluorescence or enhanced contrast, helping to identify fingerprints, biological fluids, fibers, and gunshot residues on various surfaces.

The OR-GJG4000 supports three main wavelengths: OR-GJG4000A (green laser at 532nm), OR-GJG4000B (blue laser at 445nm), and OR-GJG4000H (a combination of green at 532nm and blue at 445nm, along with CSS which is a mixture of 532nm and 445nm).

Fluorescence detection works by illuminating a material with laser light of one color (blue or green), which then absorbs this light and re-emits it as a different color. This fluorescence makes the evidence more visible and easier to detect.

Key features of the OR-GJG4000 include its design for both lab and field use, built-in Li-ion batteries for portability, DC operation capability, even light beam output, integration of three wavelengths, optical fiber operation, removable safety key, tripod mount on the handle, and adjustable power intensity.

The OR-GJG4000 operates on a 220V charger for the lithium-ion battery or a DC16.8V lithium battery pack. The built-in Li-ion batteries have a capacity of 12Ah.

The illuminating beam size specifications are as follows: Diameter at 0.5m is greater than or equal to 7cm, and Diameter at 2m is greater than or equal to 28cm.

The OR-GJG4000 is highly portable, designed with built-in Li-ion batteries and a lightweight, ergonomic handle. It also includes a carrying canvas bag for easy transportation.

The OR-GJG4000 can detect a wide range of evidence types, including fingerprints (on metal surfaces, plastic mats, and duplicating paper), saliva, seminal stains, bloodstain traces, urine traces, fibers, bone snap, and gunshot residues on textiles.

Yes, the OR-GJG4000 is designed for ease of use with features like a removable safety key, tripod mount, and adjustable power intensity, making it user-friendly for both novice and experienced forensic professionals.
