:: Apparatus >>> Dactyloscopic comparator :: Dactyloscopic comparatorA device for comparing dactyloscopic evidence collected at the crime scene with that stored on the dactyloscopic sheets in criminal records. It features two identical display channels operating on the epiprojection principle. The device can handle copies up to 38x38 mm. An enlarged image with a fixed (approx. 6.5 x) magnification is projected onto the 250 x 250 mm screen. The shape of the comparator enables inserting evidence from the smallest photocopies to evidence at any position on an A4 format dactyloscopic sheet. Two dichroitic halogen bulbs of 75 W, provided with electronic brightness control for each channel, generate sufficient luminance power to evaluate the most demanding tasks. The device is equipped with noise-less ventilation system and adjustable feet to create the optimum working conditions for long-term enduring work. To enhance the comfort of use even further the device has replaceable screens, light green to reduce eye fatigue and light blue for increased contrast of the evidence under examination. |
