I'm not sure what device the schematic shows, are those components within??
i want to know,why this lens named 0.32x, not 3.2x,not 0.6x,or any number else ?
can it be used as 3.2x or 0.6x by adjust work length and focal length ?
how can i know (or calculate)its focal length,
Answering your initial question, you'll have to change the focal length of the lens in order to change the magnification.
Using a zoom-lens might work, but as I wrote before, you have to know where and how large the exit pupil of the ocular is and the same for the reducing lens.
If those don't match you will get vignetting.
Yep, they should've mentioned Dallmeyer. But looking at the patent, I doubt they made the optics themselves as they don't claim anything optical.
I also don't read German, but an afocal setup like that in the German forum would result in imaging a different image plane than the primary image plane.
I think the idea behind is optimizing the projected image to an APS-C sensor rather than a full-sized sensor. It'd work for low NAs, but for high NA work it
will effectively change the TL, introducing unwanted aberrations.
Here's a great reference... by Leitzhttp://www.science-info.net/docs/leitz/ ... -15-64.pdf
Leitz seems so effective clearing the web of old manuals and brochures... I can't find documentation illustrating photographic systems...
That would be the intended setup.
