No cheating. Please cite the origin as well as the definition.
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.
I got no idea.
I tried Googling it and came up with nothing.
Yah got me.....
So, I give. What IS a Bortz dot.....?
Yes because we all know that Google is the ultimate authority on everything.
Never heard of it, or maybe was told it 30 years ago....
(Unless it's that big blue dot you see for hours after glancing at an open arc )
