Forensic Microscopes & System Solutions for Forensic Science

Transforming silent traces into conclusive evidence: In forensic science, precision, reliability, and the right illumination make all the difference. As the leading Swiss specialist in microscopy and optical metrology, Ryf AG provides tailored, end-to-end solutions for forensic laboratories, legal medicine, customs authorities, and research institutes.

From initial macroscopic trace screening and detailed material analysis to seamless digital image documentation: We support your forensic workflow with future-proof microscope systems, intelligent software, and custom Swiss engineering.

Core Applications in Forensic Analysis

1. Firearms, Toolmarks & Gunshot Residue (GSR)

Analyzing gunshot residue (GSR), cartridge cases, and toolmarks requires a precise interplay between optical magnification and specialized illumination (e.g., LED ring lights, coaxial, or fiber-optic lighting).

• Macro & Stereo Microscopy: Designed for rapid comparison tests and surface structure verification.
• Electron Microscopy & Elemental Analysis: High-end systems equipped with Energy-Dispersive X-ray Spectroscopy (EDS) for accurate chemical composition analysis of micro- and nano-particles.

2. Document & Questioned Document Examination

Detecting counterfeits, erasures, forged passports, currency fraud, or questioned handwriting requires uncompromised detail.

• High-resolution zoom stereo microscopes expose paper fibers, perforations, ink intersections, and subtle line overlays.
• Integrated camera systems and imaging software enable effortless side-by-side comparison between authentic documents and suspect items.

3. Trace Evidence: Paint, Fiber & Material Analysis

Micro-traces—such as paint chips from traffic accidents, textile fibers, or hair—frequently provide the crucial link in criminal investigations.

• Material & Polarizing Microscopy: For identifying layer sequences, coating thicknesses, color pigments, and optical properties (refractive index).
• Modular Sample Holders: Ergonomic stages engineered for non-destructive, secure sample handling.

4. Fractography & Failure Analysis

Examining fracture surfaces on mechanical components, tools, or glass reveals critical insights into stress causes and incident sequences.

• 3D reconstruction and confocal microscopy deliver volumetric visualization of micro-cracks, overload fractures, and material fatigue.

5. Forensic Medicine, Pathology & Toxicology

For investigations in legal medicine, toxicology, serology, and DNA extraction, we offer ergonomic brightfield, darkfield, and polarizing microscopes optimized for daily laboratory workflows.
