[Test-Equipment] OT: microscope cameras

[davec]

This isn't a traditional test equipment question but is about data collection.

I need to observe a process that takes place inside a flask. It is 
very small, so a regular camera's lens isn't powerful enough, and the 
distance from end of lens to the process is 1.5-2 inches.

Camera can be USB 1.1, FireWire 400 (IEEE 1394-1995), or baseband (NTSC) video.

If anyone has experience or suggestions of a good way to capture 
still and video images I'd be grateful.

Thanks,
Dave
