My next post after the post for infinite objective is the only solution I can think of -- use two rails, one moves the lens (vertically) and one moves the camera (horizontally) but they move in tandem, ie, if lens moves down by 5um, the camera moves forward by 5um, so that the total distance along the optical path matches what your lens requires.

I have very little knowledge of optics and optical system, so please take my ideas with a grain of salt

There may be no need to move the camera, even in a finite system. Stacking by moving the objective alone is a perfectly valid method, similar to stacking by lens focusing being discussed for use at lower magnifications.

Ray,

I have not played with finite objectives and do not know how they behave. Like I said before, I have very little knowledge about optics and optical system, all these terms are mind boggling to me

But maybe I should get some finite objectives and play with them, they seem to be cheap.

Anyways, I take your word for it, thanks.

The AmScope 4X Robert discovered, and Lomo 3.7 are nice finite lenses and very reasonable ($18 and ~$50 respectively).
