What is a bubble in the glass of a camera lens called?

A bubble in the glass of a camera lens is called a bubble, because that's what it is: if the glassmaker pours molten glass into molds, waits for it to harden then grinds and polishes the lenses to their final shape, there will be bubbles in the glass. As long as they're small and not too numerous, they don't hurt anything.Nikon invented a way to produce absolutely bubble-free glass that is not used except for the most expensive lenses. To do it, they make the glass in small ceramic crucibles. After the glass is molten, the various metals they put in the glass to affect its light-handling properties are added and the glass has gone through its cook cycle, they set the glass in a special machine that performs a process called annealing. This takes the stresses out of the glass and makes it better. Then they let the glass harden in the crucible. This takes months and is very tightly controlled. When the glass is completely hard, they haul the crucible to a very high height and drop it on a granite slab, causing the crucible and the glass in it to break into a million pieces. Once they have broken glass, they pick out the pieces large enough to make lenses out of and cut and polish it to the proper shapes.- - - - -It is called Orb. The wiki definition is as following.The term orb describes unexpected, typically circular artifacts that occur in flash photography - sometimes with trails indicating motion - especially common with modern compact and ultra-compact digital cameras.More detail... http://en.wikipedia.org/wiki/Orb_%28optics%29
