Product Overview
There are various imaging devices available on the market, such as ultra-wide spectral, ultraviolet, laser, and visual targeting reagents, which are used for the search and discovery of fingerprints, bloodstains, semen stains, and exfoliated cells. However, each device has a single function and cannot uniformly address the discovery of various complex objects, such as walls, dusty glass, dark backgrounds, and latent fingerprint and DNA traces
The SMA-QN02 all-in-one Intelligent Crime Scene Investigation Instrument is highly integrated. It uses a scientific-grade ultraviolet chip and an intelligent computing host, and combines intelligent anti-shake and image fusion algorithms. It has built-in multi-band light sources, high-power blue and green lasers, a full-spectrum lens, a white light fixed-refraction device, etc. It has 7 professional optical imaging functions, which can quickly search, photograph, and collect evidence of latent fingerprints, palm prints, trace bloodstains, saliva stains, semen stains, urine stains, bones, and other biological evidence on the surfaces of non-porous, semi-porous, and porous objects. This greatly improves the efficiency of on-site investigation, extraction, and analysis, and can meet the collection requirements of complex and diverse criminal case scenes.
Advantages
1. Long-distance and large-area fingerprint search and laser positioning function: A 40%@365 nm ultraviolet light source is suitable for fingerprint search and extraction, with a search distance of over 3 meters.
2. Closed - range fingerprint shooting and scale function：The device is equipped with a 254nm closed - range light source, which can take clearer photos of the searched fingerprints. The fingerprint texture can be further enlarged for detailed shooting. At the same time, the 254nm light source is equipped with a scale, eliminating the need for manual scale pasting during on - site fingerprint shooting, simplifying the operation process and facilitating on - site evidence collection.
3. Biological trace search function: High - purity and high - power LD lasers (445nm blue light/520nm green light) are used, with a light uniformity of over 98%. The spot diameter at 1m is not less than 30 cm, which is suitable for the search of various biological evidence such as saliva, semen stains, urine stains, and bones.
4. Directional reflection function: White light is configured for directional reflection, which is suitable for complex background removal during investigation.
5. Exfoliated cell discovery function: The white light search device for exfoliated cells is dedicated to the search and discovery of exfoliated cells.
6. Latent bloodstain search function: An 800nm - 850nm near - infrared light source is suitable for the discovery of latent bloodstains on dark - colored clothing.
7. Difficult object visualization function: A dedicated targeting reagent is configured for visual targeting of difficult objects.
