Fingerprint Comparison workstation
Fingerprint Comparison workstation

Introduction

The dactyloscopy workstation for fingerprint imaging, processing, and comparison is built on combination of USB 3 monochromatic CMOS camera with high quality Schneider Kreuznach macro lens with fixed focal length providing excellent image quality without aberrations in the resolution range 600 – 2000 PPI. This imaging unit is mounted on the column with adjustable position of the camera. Objective is focused manually. The object is illuminated with a pair of LED panels with adjustable light temperature. Image capturing, calibration, processing, annotation, measurements, and comparison are integrated into the LUCIA Forensic software. Software supports newest PC hardware and software as Windows 10 operating system and 4k monitor.
 
There are 2 alternative stages – a stage with free working area and coarse and fine focusing and a stage with a baseboard with grid and coarse focusing only.
