Microscopic Evaluation

Cold light is supplied by fibre optic cable directly to the components under examination.The examination of bullet striations for close up evaluation is normally associated with the comparison microscope, it is also used to compare firing pin indentations, extractor markings and toolmarks from the breech face.

 

The Criminalistic Comparison Microscope...

has a split-screen viewing facility with a dividing line between the two part images.The two samples are viewed on a computer monitor, when positioned to show a match, the frame can be held in the computer memory and recalled when required for the preparation of a report.

 

 

Update 2012

As of 2012 we have finished upgrading our microscopy facilities. Our new purpose built teaching room boasts eight comparison microscopes and associated equipment. We hope that these new facilities combined with our excellent teaching staff will allow us to offer an exceptional service and a valuable source of information to the forensic science community in the UK and overseas for many years to come.

 

 
 

CamScan MX 2500 - Scanning Electron Microscope

 

 

Scanning Electron Microscopy – SEM CamScan MX2500

The CamScan instrument is a research-grade analytical SEM capable of reaching 100,000 x magnification. High-resolution images of biological samples, metal surfaces, particles, fibres and material surfaces can be achieved with this instrument. This system also has EDX capabilities (above Z=11), whereby elemental analysis or chemical characterisation of a surface can be performed.
