What's the difference between UV detection light and black light?
The ultraviolet flaw detection lamp is a 365 nm long-wave UV light source designed for large-area inspection. Since its wavelength is outside the visible range of 380–800 nm, it is invisible to the human eye and appears as “black light.” In non-destructive testing applications, it is commonly referred to as a UV inspection lamp or black light.
