<p>[[NeoScan]] real-time field measurement and scanning system contains a 40 mW laser diode emitting Class 3B laser radiation at ~1550 nm. The direct output power from the fiber port of each probe channel on the front panel is less than 10 mW. The beam at 1550 nm is invisible to human being and the invisible beam can be hazardous if directed at the eye. Direct exposure of eye to the invisible laser beam must be avoided. <br>
