Universal Comparison Macroscope
Comparison Macroscope
For forensic comparison investigations

A new concept for comparison investigation of forensic objects. The COMAC with its modular design in conjunction with high optical and mechanical quality sets new standards in investigation of evidence. The modular concept allows easy adaptation of special object holders, illumination systems and documentation units.

For forensic comparison investigation, such as
• Documents
• Tool marks
• Cartridges and Bullets
• Banknotes and coins
• Illegally produced tablets (Ecstasy, PMA, synthetic amphetamines, etc.)
