The difference between 365 and 395 High-power banknote detector UV ultraviolet 365+395nm Tsinghua purple fluorescent lamp Scorpion bright flashlight 1. Different wavelengths The typical difference between these two purple flashlights is the wavelength of the flashlight light. Obviously, their wavelengths are 365nm (the eyes cannot see obvious light perception) and 395nm (the eyes can feel the purple light source) This can be seen intuitively from their names, and the difference is also the difference in flashlight parameters. 2. The colors of the irradiated items are different The light emitted by the 365nm purple flashlight is relatively weak; the light emitted by the 395nm ultraviolet flashlight is relatively strong. Generally speaking, it is easier to identify the fluorescent agent in an item when a lighter flashlight is used, while the ability to identify the fluorescent agent is not so strong when a darker flashlight is used. 3. Different uses The 365nm purple flashlight can illuminate some fluorescence that the 395nm purple flashlight cannot illuminate, such as the fluorescence on the back of the RMB. In short: 365 purple light is suitable for curing UV glue for antique banknote verification, anti-counterfeiting identification... and 395 purple light is suitable for outdoor fishing observation buoys, fluorescent night vision devices, or illuminating scorpion lamps...
