I heard that particles inside endoscopes are caused by movement of the lenses during transport etc.
Because of the rod lenses inside an endoscope are separated by spacers and the combination is hold together by a spring.
So what happens is that the spacer can move a little during transport or other shocks and therefore rub against the rod lens surface.
This will cause little particles on the rod lenses inside endoscopes. It's hard to detect without special tools.
My advice is to check you're newly received endoscopes carefully before using them into theatre as particles and sometimes even broken rod lenses are caused during transport. If you discover this before using them it's easier to claim warranty...
