The present utility model is a biometric device, specifically a device to obtain images of human palm veins. The utility model has application in biometric identification for access control and management, working time tracking, authentication systems used during financial operations, in passport and visa departments, in bank security systems, and so on. A palm vein imaging device that includes a housing, a light sensitive element and an optical imaging system, light emitting elements and the control system, wherein the palm vein imaging device contains an infrared transmission filter and a scattering filter installed above the light emitting elements and the light emitting elements are infrared light-emitting diodes emitting light of wavelength of 850 nm and 940 nm. The technical result of the utility model is increased quality of the obtained image of palm vein vascular pattern, reducing the amount of noises and distortions while imaging and as a result increased reliability of personal identification by means of the claimed device.
