2.4 mm 3D Borescope - -Hmmm
I had decided not to log in and put a comment in - - but !
I was a trained specialist on the IPLEX 3D measurement system 5 years back - - and have kept up to date with new technology since then .
If I am still up to date , the IPLEX system only has 3D presentation by way of special Video Spectacles and I think it still remains a 2D "Screen" presentation system to this day .
I am almost sure that a 2.4 mm scope if used would only be a "Fiberscope" fitted with a TV Camera and then again it would only be 2D .
These Flexible Digital Image probes and Fiberscope's are extremely unhappy in Oily
locations - - - the Image is only good when the environment is very clean !
Perhaps its another manufacturers system - - but 3D display at even 4 mm would be fantastic and almost certainly an optical specialist "Only " tool.
