Using solar blind filters can enhance the contrast of images captured using UV reflectance imaging techniques. Ultraviolet (UV) fluorescence imaging is a commonly used technique that requires a UV source to stimulate visible fluorescence and filters placed in front of the camera that block UV wavelengths while allowing fluorescing light in the visible spectrum to be recorded. An alternate detection technique, UV reflectance imaging, records the reflected UV image while blocking visible background and fluorescent emission from the object (Figure 1). Applications of reflected UV imaging include forensics, medical imaging, pollution and climate monitoring and surface damage inspection. To provide the UV illumination for such applications, a number of different sources can be used. Artificial sources of UV energy include mercury vapor lamps with UV lines at 254 nm and 365 nm, but strong visible emission lines are present at 404 nm, 435 nm, 546 nm and 615 nm wavelengths. Xenon arc lamps emit UV as well as visible and near-IR light. To perform UV imaging requires high rejection of the non-UV light from these sources and from other ambient sources such as sunlight and fluorescent light...
