Product introduction:
With a spectral response range of 160nm~1100nm,the system can conduct a wide range search and high-definition recording of fingerprints,palm prints,blood stains,urine,spermatozoa,DNA traces,exlapsed cells and other organisms on various objects.With extremely high sensitivity and super week trace detection ability.
Function introduction:
SMA-3000A can perform static and dynamic photography of ultraviolet,near-infrared spectra,and visible light.Through technologies such as shortwave ultraviolet reflection photography,longwave ultraviolet reflection photography,ultraviolet fluorescence photography,visible light spectrophotography,visible light fluorescence photography,infrared reflection photography,and infrared luminescence photography,it can achieve the following functions:
Long distance large-scale fingerprint search and laser positioning function:Using an open 365nm light source,it can clearly search for fingerprint traces in areas such as walls,cabinets,and window glass within a range of 2.5-5 meters.For discovered fingerprints,laser can be used for localization for easy detection and labeling.
Auto focus function:One click auto focus is a unique feature of this product,which allows on-site law enforcement personnel to search for various traces more conveniently and quickly,and greatly improve work efficiency.
Close range fingerprint shooting and ruler function:The device is equipped with a 254nm enclosed light source,which can take clearer photos of the searched fingerprints,and the fingerprint texture can be further enlarged in detail for shooting.At the same time,the 254nm light source is equipped with a ruler,which eliminates the need for manual pasting of the ruler when taking fingerprints on site,simplifying the operation process and facilitating on-site evidence collection.
Potential blood stain search function:The device is equipped with an infrared 850nm light source,which can effectively detect blood stains on objects such as walls and clothing that cannot be detected by the naked eye.
Biological trace search function:For the search of biological traces such as footprints and saliva,the device is equipped with a five band light source(395nm,445nm,532nm,850nm,940nm)and filters(410nm,450nm,500nm,550nm,600nm,650nm,700nm),which can be used to switch the light source and filter for different traces.
File verification function:With an 850nm light source,it is possible to effectively see the text that has been drawn with a non carbon pen,as well as eliminate the text added with non carbon pens in the file,and directly see the content of the file itself.
Features：
Ultra high sensitivity:
Adopting advanced UV enhanced electronic multiplication noise reduction technology and full spectrum ultra high definition UV enhanced imaging components,the image has no deformation,extremely high clarity,and high sensitivity in all bands,254nm/312nm/365nm covers the entire ultraviolet range,especially with a sensitivity of over 60%in the entire ultraviolet region.
Wide range search and macro shooting:
The 78mm high achromatic quartz optical objective configured by the system has outstanding high-definition imaging effects from ultraviolet to visible light to infrared.This objective can achieve long-distance and large-area physical evidence search within 10 meters(such as footprint shooting),and also has the function of shooting at a macro distance of up to 15 centimeters,achieving detailed magnification shooting such as fingerprint features and file verification.
HD output:
25 frames/second real-time high-definition video image output,4 million(2048*2048)ultra clear static image output;Uncompressed RAW format,high-speed SSD solid-state drive used for recording and saving video and image data.
Humanized design:
It can be operated by a single person,allowing for real-time search,observation,and shooting without the need to replace any components.
Image processing software platform:
Equipped with specialized criminal evidence image processing software,it provides an advanced platform for post processing of evidence images.
