In Generally,Can checking up Paper money for under 410 nm of Violet LED. But every one should know that different ultra-violet are different Result. where is the pathos?

The detection of fluorescence reflection of the color difference are their main factor. The violet led was “gray white fluorescent” for over 400nm(or equal to  400nm). it under 400nm lower(reflection fluorescence color tends to the “golden” low in 400nm)visual effect is more obvious, lower the band is getting higher price. So Detection equipment wavelengths of Violet both have 380~410nm in town.Violet LED around the Paper money as follows; major in currencies such aspound, US dollar, euro, franc used 360-380nm Violet LED, 365nm effect best in generally .pound, dollar, euro, and franc able to detection and 390nm or above the 390nm is no reflection fluorescence,380~390nm very weak. so they looks unfit for detection duty.
