1) Special filter: Filters various wavelengths within the UV range to ensure pure 265nm wavelength, maximizing performance.
General UV products have a wide wavelength range.

*Light below 380nm is called ultraviolet (UV) light, and cannot be seen with bare eyes.

This item uses ultraviolet light, not visible light, to generate inductive light and visualize foreign substances and oil. It also uses a UV LED with a peak wavelength of 365nm, which is effective in visualizing foreign substances and oil, and uses an optically designed deposition lens to block unnecessary wavelengths such as visible light, and irradiates only short wavelengths with a peak wavelength of 365nm. Since it contains almost no visible light, the light may appear dark (weak purple) compared to UV lights from other companies, but the UV intensity is very strong.

2) 15m long distance: It emits UV light up to 15m, allowing it to detect objects that are difficult to approach or far away.
Normal UV products on the market have a very short light range, so they cannot shine far.
