This modification removes the UV/IR blocking filter ( Hotmirror ) from your camera and replaces it with a neutral filter. With this modification the maximum sensitivity of the camera sensor for UV radiation, for visible light and for infrared radiation is guaranteed. The sensitivity of the sensor starts (depending on the model) at approx. 300-320 nm and ends at 1,100-1,200 nm.
After conversion, the camera is suitable for all forensic examinations. This includes building forensic examinations, forensic medical examinations or even art restoration techniques. For a useful application, however, suitable spectral filters (long-pass, short-pass or band-pass filters) and, if necessary, special light sources are always required. A sophisticated and widely tested filter set for building forensics is distributed by Prof. Andreas O. Rapp -> available here.
