As the saying goes: "Workers must first sharpen their tools if they want to be good at their work"! Buying a purple lamp bead flashlight is also not listed, so the editor will introduce to us why we should choose 365nm related matters about the external LED lamp bead flashlight. .
A qualified TANK007 purple flashlight = accurate 365nm wavelength + satisfactory ultraviolet light intensity + satisfactory concentration. The purple flashlight has various uses. For our love jade players, we need a version with a wavelength of 365nm.
The UV LED manufacturer tells you that 365nm UV is classified as invisible light and cannot be seen by the human eye. Due to the manufacturing process, the ultraviolet light declared by the LED is in a peak shape. It mainly converges at a wavelength of 365, and there will be a small amount of visible light exceeding 400nm. Therefore, the purple flashlight will also declare weaker visible light, not simple ultraviolet light. Therefore, after turning on the qualified 365nm flashlight, it should be a tiny white light with a little blue. If the brightness is high, it indicates that there is a problem. If the declared light is blue or purple, then there is also a problem.
A good purple flashlight also has outstanding talents for gathering. It can illuminate as much ultraviolet light as possible in the same direction and add the ultraviolet intensity per unit area. This is about us inquiring about southern red, amber, dense wax, turquoise, jade, etc. A lot of help.
During the fine inspection of high-end items such as jewellery, jade, jade, amber, invoices, stamps, flaw detection (industrial use, fine scar differences in parts), fluid trace detection (oil stains, criminal investigation detection, etc.), it is necessary to use it for fluorescent agent detection , Because there is no purple light, the talent is accurate and the difference is delicate. For other special occasions, it is necessary to use 365nm 375nm violet light (generally 370~380nm) when specifying 365nm. The price of 375nm violet light will be much cheaper than 365nm. 375nm is a threshold of the price of violet light.
375nm UV LED is also suitable for various authenticity differences. It can check foreign currency, jade, jade, invoices, etc. It is not as effective as 365nm wavelength, but slightly purple visible light, although the effect is worse than 365nm! But the cost performance is better! High, but it will be better than 395nm on curing UV glue. In fluorescent printing, 375nm is very cost-effective and 395nm violet (generally 395~405nm).
