Applications of Black Light in Authentication and Counterfeit Prevention: Fluorescence in Research Fields
We are increasing the situations in which we use LEDs that emit wavelengths that excite fluorescent agents!
Traditionally, ultraviolet light has been widely used for fluorescent reactions; however, considering the development of fluorescent agents and the dangers of ultraviolet light, there has been an increase in fluorescent agents that react to near-ultraviolet light. Consequently, utilizing the property of LEDs to emit specific wavelengths, there has been a rise in the use of LEDs that emit wavelengths that excite fluorescent agents for observation. In this context, our company can provide custom-made LEDs that peak at wavelengths in the visible light range, such as 445nm, 465nm, 505nm, and 520nm, in addition to ultraviolet light. If you can provide the excitation wavelength of the fluorescent agent you are using, we will prepare a suitable fluorescent handheld light for you. 【Features of Our Black Light】 ■ Custom-made options available for LEDs that peak at wavelengths in the visible light range, such as 445nm, 465nm, 505nm, and 520nm. ■ We offer suitable fluorescent handheld lights (note that some deep ultraviolet and unavailable wavelength ranges may exist). *For more details, please refer to the related links or feel free to contact us.

basic information
【What is Black Light】 - A general term for light that emits primarily wavelengths shorter than 400nm in the visible spectrum (ultraviolet light). - It produces fluorescent reactions that cannot be observed with visible light, and various reactions can be seen depending on the object. - It is widely used for various purposes, from hobbies like fluorescent verification and lure phosphorescence to counterfeit detection of banknotes and industrial ultraviolet flaw detection lamps. *For more details, please refer to the related links or feel free to contact us.*
