Advice and thoughts about UV-C light or wand.
I collect older camera equipment and have seen where some people use UV-C lights to treat their lenses and cameras to prevent mold or fungus in the lenses. I have also seen how some use larger bulbs to treat rooms like in a hospital.

Based on what I have read I am pretty convinced I am going to go ahead and get at least a wand to treat my gear.

Was wondering if anyone else has any recommendations, ideas or tips?

The Katadyn Steripen uses UV light to kill viruses quite effectively when used in water. Whether it works for mold is a good questions. It can’t hurt.

“Normal glass (as used in windows) is transparent to UV radiation to a wavelength of about 330 nm (UV-A). The transparency is quite high so almost all UV-A light will pass through glass. Below 330 nm (UV-B and UV-C), almost 100% is blocked by normal glass.”

Don’t know about camera lens glass, but suspect that it’s nearly opaque to UV-C. Might help on the outer lens surfaces.



Serious about crackers.

Alot of people use UV filters when taking photos and I have read to remove them before treating with UV light so that the light can get thru.
