Ballistic Comparison Stage

This very comprehensive stage replaces the standard door mounted unit and can be easily changed in minutes.
It is deigned to accept a range of shell cases, bullet and cartridge cases and allows two samples to be mounted side by side for detailed comparison. Each sample can be independently rotated through 360º and their relative heights adjusted. Both samples can be tilted from 0 to 120º to view underneath shell flanges for extraction marks.

Comparisons are made by image overlay techniques after which the results can be archived for subsequent recall for future inspection and comparisons of further evidence.

By removing the comparison sub stage the ultra long working distance platform can be used for very low magnification work such as document investigations, fingerprints or complete postage stamps.

The X and Y movements are controlled through high-speed motors.
