Luminescence sensor
SMARTEYE® STEALTH-UV™ Tri-Tronics

The SMARTEYE® STEALTH-UV™ is a special purpose luminescence sensor designed to detect the presence of invisible fluorescent materials contained in special chalks, inks, paint, greases, glue, optical brighteners found in labels, paper, tape, string, etc. The STEALTH-UV™ luminescence sensor 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.
