I finally had a bit more time to work on this.
I tried the adjustment screws. Despite appearance of threadlock they were not locked. Simple attempts to adjust them did not help at all.
I performed another experiment. Two post-it notes of different color were aligned and attached to each other. When looking at the composition edge on you should see one color with one eye and different color with the other. I used this to confirm that I indeed have a 3D image.
Than I decided to go for broke and pen the mantis. LED light are very easy to remove, just one screw and they pull out together with connector. Then lens carousel is another screw. Additional 4 screw separate the mechanism used switching lenses. It almost looks too complicated of a contraption for the simple function that it serves.
Viewing hood is easy to remove and that exposes a large lens that was held in place by that hood. It can now be removed.
Then two screw from the top and two from the bottom remove the bottom panel that is holding two mirrors at 90 degrees angle. I believe it is responsible for splitting image into left and right eye view. One mirror is fixed and the second is adjusted by 5 screws I shown before. They are the screws that are adjustable through desiccant port. In fact after looking at the insides on the microscope this is the only adjustable part.
With bottom removed you can see a number of flat mirrors, a large panel of flat glass that i think serves as semitransparent mirror. These mirrors are very hard to photograph. I may have to draw a diagram. So far I still do not understand the optical design.
The good news so far is that the microscope is fairly clean inside beside few strands of spiderweb. There is nothing obviously broken or out of place.
It is beautifully designed, appearing simple, elegant, yet mysterious.
I will keep exploring...
