The SMARTEYE® STEALTH-UV
is a special purpose sensor designed to detect the presence of invisible fluorescent
materials contained in special chalks, inks, paint, greases, glue, optical brightness
found in labels, paper, tape, string, etc. The STEALTH-UV
contains an ultraviolet (UV) solid state light source that is used to excite the
luminescence in materials to fluoresce in the visible range. The sensor's detector
then responds to the visible fluorescing light. When the received fluorescing light
level as displayed on the Contrast Indicator reaches a level of "4" or
above, the NPN and PNP output transistors will switch to the opposite state.
