The Model 228 lens from Resolve Optics provides high performance in
both the UV and visible wavebands, enabling forensic scientists and
crime scene investigators to identify and focus on a target in the
visible and then quickly slide the UV filter across to take images in
the UV without having to refocus.
The interaction between materials and UV light makes reflected-UV very
useful for a number of applications in forensic investigation including
imaging of latent fingerprints, imaging of bite marks and other pattern
injuries on skin and imaging of shoeprints on surfaces where
visible-light contrast is low.
By using a novel telescopic focusing mount the Model 228 lens gives a
large movement in an extremely compact form. This provides the
lens with the capability to image objects from infinity to 1:1.25
magnification without using add-on adapters.
Offering a wide field of view (8.3° at 1:1.25 magnification up to
16.6° at long object distances) the lens offers unmatched
high-resolution macro images for fingerprinting and human skin damage
applications in particular. Because of its wide field of view and
the high transmission qualities of the lens coatings used the Model 228
lens is considerably more light efficient than other longer focal
length lenses offering an identical view.
The Forensic UV Lens offers a true high-resolution crime site macro
viewing capability by imaging onto a RUVIS scope with a 1:1 lens
magnification whilst exactly matching the optical resolution of both
lens and image intensifier.
