    I have no idea, so I'm going to guess and then google it.
    My wild guess is--
    A Bortz dot is a term for the F1 point used in bench focusing to describe the theoretical point source (the dot the light would originate at), named for Alfred Charcoaldabs Bortz.

    While I still have no idea, a wikipedia re-direct took me from "Bortz" to "Diamond".

    Sorry to disappoint but I actually have no idea!
    (Unless it's that big blue dot you see for hours after glancing at an open arc ;) )
