Must use non-indented top plate with MS9400.
Also must add quantity of 2/ea 0.020 inch spacers to stage posts and back mount. With these spacers, focal point of slide in I-9408B insert is at 18719.04 from top travel. Complete travel range is to 20000. Large condenser can also be focused with this insert.
Slide sits too low to focus
Condenser hits standard leadscrew coupler, need to use side mount coupler
With S-4016 insert that sets slide flush with top of stage, focus is at 15029 so you still have 470um of downward travel, Kohler is still way out
You can get Kohler if you space up the lens by 7mm with tube spacers as shown in photos 3/12
Can get Kohler and focus at 18874 without adapters with I-4013 insert
I-4012 insert focus at 17,072 would need to space up top lens approx. 3-5mm to get Kohler. If you unscrew the top lens all the way and just set it on the holder you can get Kohler
PZU Post Mount
I-4012 insert focuses at 19042 without brass/shim stock spacers Kohler is obtainable
With 0.040 spacers at 3 points and I-4012 Kohler is still obtainable and focus is at 18023
