Hi Albert…….my video is 2 years old and basically was a 17 minute lecture that was using the scope with the erbium and was from my beginning days.

If you wait until September 12-14th you will see much better stuff if you go to Vegas for the LVI meeting.

It should be an excellent meeting in my mind.

THere is a ton of information here on this site and in addition I am happy to help (time permitting ) at glennvanas@shaw.ca

Hope that helps.

Glenn
