And if so, it would seem one could cobble together the camera, X/Y table, software to make one's own video system at low cost such that even the price would be no advantage of the OC unless thinking in terms of buying an older used OC. Thoughts ?

Optical comparators are obsolete.
What we need is 100 megapixel cameras, LCDs with higher resolutions and the bandwidth to pump this huge amount of data in real time.

Its 2013. We have all those things.
That is neat...probably breathtakingly expensive though. As an aside, the salesman in the video does a really good job of explaining the system in a quick concise manner.This youtube video: CCP 4 Minute Demo! - YouTube
shows the latest in OC technology.
The ability to overlay CAD data is very interesting.
Interesting. Can you find out exactly what he has ? Just wondering if it's an "antique" system from the early 90's or something more current.One of my customers has a video measurement system but has reported large measurement uncertainty when the features being meaured are different distances from the lens, something to do with the focal length?

Its a depth of field/magnification ratio problem and newer stuff will not fix basic optics/physics laws that have been known for 100's of years.
The nicest thing about a pure optical system is that it will pass a almost unlimited amount of data through in parallel at the speed of light.
Most of my vision systems run 500-1000x which is barley good enough to resolve a tenth.
What kind of features are you trying to detect? At a pixel-pitch of 5μm, with one-to-one magnification, everything else being equal, you should be able to resolve down to 10μm at the Nyquist limit. 10μm is approximately 4 tenths.
but it is great fun and sure stretches the ole brain.
