[交流] 验钞的紫外手电筒可以照EB胶吗？能看到吗？

如题，光强够不够呀还是对紫外有什么其他的特殊要求

要解决此问题，需要查下两方面信息：
1，验钞机参数:
常用检验钞票、支票、发票等票据使用发射波长365nm的紫外灯管。（医院常用的紫外灯称紫外线消毒灯，它的灯管紫外线波长为254nm。）
2，EB的参数 :
As with most fluorescent compounds, ethidium bromide is aromatic. Its core heterocyclic moiety is generically known as a phenanthridine, an isomer of which is the fluorescent dye acridine. Absorption maxima of EtBr in aqueous solution are at 210 nm and 285 nm, which correspond to ultraviolet light. As a result of this excitation, EtBr emits orange light with wavelength 605 nm.[2][3As with most fluorescent compounds, ethidium bromide is aromatic.
