These are the objectives people usually refer to. Edmund Optics seems to be the official distributor although I'm not sure they carry all types such as the BD Plan.

The important thing to know about these is that if you drop one on your foot you'll be balancing the hospital bill against the optics damage. At at list price of over $20,000 the 80X wins for most expensive COTS objective.

For machine inspection. They look similar to the LWD objectives.
They do seem to make a few “standard” objectives.
