The Model 228 lens from Resolve Optics provides high performance in both the UV and visible wavebands.
The lens allows 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 compact form. This provides the lens with the capability to image objects from infinity to 1:1.25 magnification without using add-on adapters.
Due to its wide field of view and the high transmission qualities of the lens coatings used, the company claims the Model 228 lens is considerably more light efficient than other longer focal length lenses offering an identical view.
