Can anyone tell me If I can buy a UV light that is invisible to the naked eye?

[David]

Essentially I want to buy a UV light that doesn't have that annoying blue glow, I just want the UV light that is invisible to the naked eye like infrared light. I read a bit about it and from what I read what I'm looking for is possible. A lens that filtered out the blue/violet light out of a black light would also be fine. Looking for leads.
 
Why I want one?
 
Science experiment... related reasons.  


I know they are dangerous, I will be taking all necessary precautions so no need to worry! Just looking for how to go about sourcing such a light/ filter lens. 


First time using this forum, hope I'm in the right spot.
