UVCorder TM
The UVCorder™ consists of a standard Sony Camcorder equipped with the Sony Intelligent Accessory Shoe, upon which is mounted a special ultraviolet camera module, or UVM. The shoe provides electrical power to the UVM, which plugs into the shoe much like an accessory light or flash unit. The UVM contains a silicon CCD camera with enhanced ultraviolet response in the 300-400nm range, and a peak response at 370nm. A special filter rejects both visible and infrared light from reaching the sensor. This means that the UVCorder™ can be used in situations where the ultraviolet illumination is lower than the visible or infrared illumination. For example, on a clear, sunny day, the UV images formed by the camera are 99% ultraviolet in their spectral content. A standard black light can be used in indoor situations, since by design most interior lighting emits little UV light.
Live images from the color video camera and the UVM are displayed on a 3.5” LCD screen on the camcorder. UV stills at 640x480 pixels can be recorded onto a Memory Stick Pro Duo with the touch of a button, as well as video to a 60 minute mini-DV cassette tape.
The UVcorder™ will run for about 2 hours on the Sony Infolithium battery included with the system. Total system weight is 880 grams, or about two pounds, not including the rugged, watertight Pelican carrying case that comes standard.
The UVM accepts C-mount lenses that have UV transmission. The UVCorder comes standard with a 16mm focal length uncoated glass lens designed for machine vision camera applications that has good UV transmission. The lens has an adjustable iris that ranges from f/1.6 to f/16 and then to fully closed. Other focal length lenses are available.
