Product Profile:
The full spectrum digital photography system uses quantum technology to install the ultraviolet light sensitive unit synchronously at each pixel of the Canon 60D camera photosensitive chip, so that the spectral range of each unit can reach 200 to 1100 nm, and the imaging resolution can really reach 18 million effective pixels, which can be displayed on the LCD screen, especially the package. Real-time image with wide spectrum including ultraviolet ray.It is suitable for photography, fingerprint, trace, document inspection and other professional fields.
Performance characteristics:
(1) Nondestructive testing
The camera can directly feel the short-wave ultraviolet radiation without any brushing and displaying of fingerprint trace. It can better meet the requirement of non-destructive extraction advocated by modern criminal science and technology.
(2) Convenience and rapidity
The operation process is the same as that of ordinary digital camera. It is simple to operate and can realize real-time observation, real-time shooting and real-time storage. To truly achieve "what you see is what you get" in ultraviolet observation photography is a true ultraviolet observation camera.
(3) Humanized Design
Humanized cup-top ring ultraviolet lamp greatly reduces the damage of ultraviolet to skin and eyes. Not limited by the incident angle of ultraviolet light, it greatly facilitates the shooting process and improves the working efficiency.
(5) Widely used (including special material handling)
The eight categories of objects stipulated by the Ministry of Public Security can be easily extracted from fingerprint evidence images of various non-permeable smooth and semi-permeable smooth objects. Such as: paint wall, aluminium alloy material, stainless steel material, printing paper, glass, mirror, oil machine glass, plastic, tape, photographs, paper, paint wood, ceramics, etc. In addition, for the following special objects, there are also other trace extraction methods can not achieve the effect.
_Wall fingerprint: Including imitation porcelain wall, lacquer wall and not very rough lime wall, whether the fingerprint is fresh or not, can be photographed quickly.
Dust fingerprint: It generally exists on the surface of objects that are inconvenient to bring back to the laboratory. It can not be treated by brushing and fumigation. It can be extracted quickly and easily by ultraviolet photography.
_Adhesive fingerprint of tape: The process of conventional processing and photography is complicated, and the viscous surface fingerprint can be extracted directly and conveniently by full spectrum camera.
Photo fingerprint: Traditional methods have background interference and are difficult to extract. Ultraviolet photography can remove background, and the effect of fingerprint is better.
Mirror Surface Fingerprint: This kind of fingerprint is very easy to find, but it is difficult to take pictures with great interference. It is easy to get ideal contrast and clear pictures with this camera.
(6) Infrared Document Inspection
Identification of different ink additions and alterations, discovery of encrypted text on black cloth
