Check out this article. It will be nice when they incorporate this into scopes.

Thanks for the link.....very interesting. This is a badly need item for rifle scopes indeed.

Might make it tough for the index coating to adhere, but this crap we have have been doing for 20 years filling the tube with something very cold is about silly. Good link.
