  • Patent number: 6862093
    Abstract: A forensic light source uses a pair of filter wheels to achieve a combination of the characteristics of filters on different wheels and may include a housing which supports the light, filter wheels and other parts with shock absorbing members such as rubber washers or the like to achieve a shock resistant housing. A light source and a plurality of light filters are contained within the housing. The light source is powered by an external power supply, thus making the light source light weight.
