It looks like the Sony ICX413AQ CCD has a plain glass window from the factory (good) and the Orion folks put their own IR cut window over that. So it looks like your JPEG indeed shows a very closely spaced IR filter that is not sealed. There is no other way for dust to get in this space, I would have to have it infront of me to see how the IR filter bonding is done.
If it's under warranty send it back.
