SpectraScanner

 

The SpectraScanner is a handheld imaging system that has all the functionality of the UVScanner, plus an additional near-infrared viewing capability. This dual-band imager uses two separate cameras, one tuned for longwave ultraviolet, the other for near-infrared. The operator toggles a selector switch on the top of the unit to change bands. As with the UVScanner, the SpectraScanner 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 SpectraScanner is equipped with a 396nm longwave UV LED flashlight and a 830nm near-IR flashlight for scene illumination in the two wavebands. The useful range of the longwave-UV flashlight is approximately 10 feet for a typical scene with 40% longwave-UV reflectivity. The near-IR flashlight can illuminate scenes up to about 50 foot range, and the SpectraScanner can be used as a covert night vision device in the near-IR mode. The eyecups on the back of the SpectraScanner 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 SpectraScanner is momentarily not in use but is still powered on.
