Introduction

1.This product adopts a super large scientific research level image transmission sensor. With a spectral response range of 150nm~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.With the reagent developed exclusively, the system breaks through the traditional ultra-wide spectrum of the object restrictions,permeability objects and rough surface can also be search and photographed.
2.The back illuminated SCMOS UV sensitive chip,professional full spectrum objective lens and multi band light source of the system can support high definition imaging in the range of deep UV,visible light and near infrared spectrum.It can realize the functions of long-distance large area finger palmprint search,close(closed)fingerprint shooting,medium distance potential blood trace search,biological trace search,document inspection and so on.
3.The integrated design makes the equipment more compact and portable while meeting the purpose of multi-function.Thus,it makes up the disadvantages of the existing ultra wide spectrum equipment in the market,such as large size,heavy weight and complex operation which cannot adapt to various complex field environments.

Specification

Imaging component

Spectrum corresponding range Effective spectrum corresponding range: 150nm~1100nm;The average sensitivity response is 70% in the ultraviolet region, especially 60% at 254nm and 55% at 365nm.
Electronic times stronger noise technology Using a science-grade CMOS imager with large target surface and large pixel with ultra-low illumination.At the same time, the background noise is separated by scientific digital FPGA and DSP noise reduction technologies, and the clear high-contrast image is obtained.No refrigeration and no multiplication tube enhancement are required to obtain continuous high-definition full-spectrum physical evidence images.
Sensor size High-sensitivity UV enhanced scientific grade CMOS sensor is adopted, with single frame resolution of 2048*2048. The image target size is 1 inch diagonal, and the pixel size is 5.5 microns.
Image processing The main machine of the recording system is equipped with an image automatic processing button, which can automatically adjust the image. 
Shutter type Electronic shutter, exposure time automatically or manually adjusted.
Video and image output 1080P 25 frames/second real-time video image output, 2048*2048 4 megapixel real-time single frame photography.

It is fully compatible with special optical objective lens for field search, observation and magnifying shooting of detailed features

Focal length/Passing wavelength 35mm/ F2.0 fully compatible quartz lens, through the wavelength of 150nm-2000nm,5 meters long range trace material evidence search, discovery, positioning in the camera.
Achromatic correction Achromatic, UV/visible/infrared correction, the image is transparent and sharp.
Macro shooting Imaging distance from 15cm to infinity, large area search to fingerprint full screen, as well as file inspection details amplification, just adjust the focus can be the whole imaging.
Integrated design UV-light source, optical objective and color filter integrated design, compact and light.The full spectrum excitation light source can be customized according to user requirements.
