we use 365 nm uv led in this product , 365 nm purple light is relatively weak, and only on paper containing fluorescent agent can the obvious purple light appear.The visible purple light can be seen at 395 nm under any irradiation.
and how to choose the LED of the matched wavelength suitable for you? we can see the difference from 365nm and 395nm
The left is 395nm, the right is 365nm
we can see the huge difference from the picture above,365nm is much clearly than 395nm ,395 nm has more violet light
Fluorescence detection: 395nm will see fuzzy fluorescence lines and 365nm is much clear and distinct. 395 nm has more violet light than 365 nm. The violet light in the light can mask the fluorescence reaction of the detected substance, resulting in blurred appearance.
The left is 395nm, the right is 365nm
The purple light at 395 nm looks a little more obvious than that at 365 nm.395 nm has more violet light than 365 nm.
