We now require users to sign out all oil immersion lenses to try and
prevent these kinds of experiences. We think the problems associated
with keeping the objectives off the scope aren't as bad as the problems
caused by users accidentally damaging these objectives when they're on
the scope. We still have about one objective damaged each year; if we
can track down the responsible user, we charge them.
