Forensic Comparison Trinocular Microscope (WFM-30)
This microscope, the Forensic Comparison Trinocular Microscope WFM-30, is designed for precise side-by-side comparison of microscopic evidence. By overlapping and joining two objective fields into one comparative view, it enables investigators to detect even the smallest differences in bullet markings, tool impressions, stamps, and other forensic samples. With its wide magnification range, advanced illumination modes, and trinocular imaging support, it is a powerful instrument for forensic laboratories, crime investigation units, and material comparison analysis.
