UV polymer cement cures within a few seconds after applying a UV light source. Once cured it is completely inert. It is literally faster than superglue which can take minutes to set up and bond and from there it takes days to actually "cure". And like we've been talking about, it risks ruining your camera filter if the fumes exuded during cure affect the dichroic coatings.
The technique with UV cement would be exactly the same as you used with the superglue. Apply a tiny bead of UV glue with a toothpick but instead of waiting for it to dry you hit it with UV light for a brief time. Done!
I sounds like you've never used the UV cement you've got or you would know how fast it cures.
