I just want to verify what the fully extended length is and the fully contrated length is on the 146-200, from one end to the other. Thanks much!

Response from Jeremy at Thorlabs: The total length of the micrometer does not change. The only thing that changes is the distance between the end to the mounting barrel. You can see the drawing for 146-200 at, which shows the view at the minimum position.
