NEW SceneScope RUVIS UHD System from Spex <strong>Forensic</strong>s<br />

The SceneScope RUVIS UHD is a 16MP Ultra High Defini on camera<br />

with 4960 x 3324 pixel resolu on, and a full frame chip. It<br />

includes capture so ware with 3 user selectable modes: Fast<br />

Viewing for placement, Focus on the evidence, and High Detail<br />

for Capture at High Resolu on and High Dynamic Range.<br />

The SceneScope RUVIS UHD is a 16MP Ultra High Defini on camera with<br />

4960 x 3324 pixel resolu on, and a full frame chip. It includes capture so -<br />

ware with 3 user selectable modes: Fast Viewing for placement, Focus on<br />

the evidence, and High Detail for Capture at High Resolu on and High Dynamic<br />

Range.<br />

SceneScope RUVIS UHD devices use 254nm UV light but unlike <strong>Forensic</strong> <strong>Light</strong> <strong>Sources</strong> they are not detec ng fluorescence. Instead<br />

the device looks for the reflec ons and sca er of the 254nm light off of the fingerprint ridges. The System can detect fingerprints<br />

on most non-porous surfaces prior to any treatment or a er a cyanoacrylate (Superglue) fuming. Fuming is required when preliminary<br />

examina on yields no results. The two primary RUVIS applica ons are untreated prints on most non-porous surfaces, and<br />

cyanoacrylate (CA) fumed prints.<br />

Smooth, Non-Porous Surfaces<br />

The SceneScope RUVIS UHD Camera allows the<br />

detec on of latent prints, prior to treatment.<br />

This is possible on surfaces that reflect light<br />

very well and do not absorb prints. That is to<br />

say, surfaces that are smooth and non-porous.<br />

Untreated prints with residual moisture show<br />

as white reflec ve ridges on a black background.<br />

Untreated oily prints appear as strong,<br />

black ridges on a shiny background. As<br />

surfaces become more rough or more porous<br />

“superglueing” the print may extend the range<br />

of surfaces on which RUVIS will work.<br />

Detects Latent Prints<br />

The two primary RUVIS applica ons are the detec on and capture of untreated prints on most non-porous surfaces, and cyanoacrylate(CA)<br />

fumed prints. Print collec on can be performed on surfaces such as plas c bags, s cky sides of tape, glossy magazines,<br />

photographs, linoleum le, compact disks, credit cards, etc. – Cyanoacrylate treatment (fuming) will further enhance the<br />

detec on by RUVIS.
