You might have trouble catching one to clip a probe to it. 
Assuming you mean ultra-violet, perhaps one of these would help:- SparkFun UV Sensor Breakout - ML8511
Do you mean oscilloscope or microscope?

I actually had the pleasure of trying one on myself once. It tingles a bit. An extended treatment was not possible due to the age of the instrument.
@mohammadgh95, you can always spare yourself the mockery and digression by posting links and detailed information. Help us to help you better.

Ah, thanks, I inherited two such devices from my grandpa, with a couple of glass tubes. Unfortunately the transformers became unusable now, due to almost organic insulation. Nowadays ignition coils might be usable instead?
I still don't understand the use of an oscilloscope with such devices

From an antique Master Violet Ray manual c. 1920 comes this treatment advice: Brain Fog - Use Applicator No. I over forehead and eyes. Also treat the back of head and neck with strong current in direct contact with the skin. Treat the spine and hold the electrode in the hand. Ozone inhalations for about four minutes are also of importance.
Thank you for that link, MarkT.
I could do with one to cure my "Brain Fog", lol.
