Product Overview
The VF10 is a questioned document examination microscope designed for stamp and stroke sequence analysis, printed document examination, paper material inspection, stamp examination, and trace evidence analysis. It combines multiple observation methods to support detailed document and material examination.
Key Highlights
Multiple observation methods in one examination platform.
100×–3200× Magnification
Supports observation from broader visual inspection to highly detailed microscopic examination.
Extended Depth Observation
Helps examine overlapping marks and upper-lower sequence relationships in documents.
Fluorescence & Coaxial Observation
Combines fluorescence observation and coaxial observation for document examination tasks.
3D Imaging Reconstruction
Supports microscopic three-dimensional imaging and reconstruction of examined materials.
Illumination and Observation Modes
VF10 supports coaxial light, gooseneck white light, blue and green excitation light, and transmission light for different document and trace evidence observation needs.
