UVCorder TM
The UVCorder™ consists of a Canon Vixia Camcorder equipped with the Canon advanced accessory shoe, upon which is mounted a special ultraviolet camera module, or UVM. The shoe provides a mounting base for the UVM, which plugs into the shoe much like an accessory light or flash unit. The UVM is powered by its own lithium ion battery. 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 2.7 ” LCD screen on the camcorder. UV video can be recorded to a 60 minute mini-DV cassette tape.
The UVcorder™ will run for about 2 hours on the lithium battery included with the system. Total system weight is 880 grams, or about two pounds, not including the rugged, watertight carrying case that comes standard with the system.
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/1.4 to f/16 and then to fully closed. Other focal length lenses are available.
UVScanner TM
The UVScanner is a new product offering for Oculus Photonics as of February, 2010. The UVScanner is a handheld imaging system that is more rugged and man-portable than the UVCorder and is designed for greater ease of use if the goal is to scan a scene in the near-UV band. The UVScanner is not a recording device, but it does have an auxiliary SMA output that can be used to attach it to a recording device such as a DVR, or an external monitor. The UVScanner is equipped with two 396nm LED flashlights for scene illumination. The useful range of the flashlights is approximately 10 feet for a typical scene with 40% near-UV reflectivity. The eyecups on the back of the UVScanner are designed to close off when the device is not pressed against the face. This keeps dust off the display lenses and also prevents light from the displays from illuminating the room when the UVScanner is momentarily not in use but is still powered on.
