Re: What in the Reichert is this?
That is an alignment tool for the HBO lamp used in fluorescence. It allows the arc from the lamp as well as the reflected arc from the mirror to be position for the best spread over the objective and ultimately the sample.

Re: Leica DM2500 condensers
Relative to the comparison of 30w vs.100w Recall the intensity is proportional to the square of the distance the lamp is from the object. The 30w lamp is located right under condenser on the DM3000 while the DM2500 has the lamp house mounted on the rear of the scope, some inches away. It would be di...

Re: 10 euro mystery microscope
One eye tube for the binocular is focusable. That would account for the difference in height. Focus the microscope using the the right eye tube first, don’t worry about the left side. Once the object is I focus, then use the left eye tube to focus your eyes to match the right side. The height should...

Re: Reichert stereo microscope
There were three different colors associated with the Zetopan.

That is a Zetopan-Pol. The shape of the base for the Neonet is more founded and the Zetopan has two levers for TL/IL deviation on the base near the vertical attachment point. Typically the tube attachment would rotate 90 degrees from side to side, in this case the Pol tube is fixed for quantitative ...

Re: Wild m420 vs wild m8 vs wild m10
Keep in mind, the M420 is a macro scope, while the M8 and M20 are stereo microscopes. Although the magnification range is comparable, the M420 is not inherently more difficult to work with, it is a difference of a 2d vs 3d image presented to the eye.

Re: Reichert diastar 420 sony camera adapter
Yes, that is the photo eyepiece tube. Is it threaded on the top? If so, it probably the is the C'mount rather than an eyepiece tube.
What is the process for inserting an image on these threads? I see the image icon, but it doesn't offer a way to pick a file.

The IPD adjustment on the Series 10/ 110 and 400 activates the movable telelens, so there is no change in the tube length associated with the change in the IPD setting. Previous comments on the difference in the Series have been knowledgeable and mostly spot on. Here are a few other things to consid...

Yep, that is correct. The viewing tubes with dual adjustable eyetubes were essentially for use with the Dual Viewing system. Otherwise, a single focusing eyetube was used on the Trinocs.

It is the same as the WP 10x/20 with one exception. It is focusable, so a reticle could be inserted and focus compensation could be made because only one eyetube on the Microstar IV/ Diastar is focusable. Notice the knurling around the top of the eyepiece so you could grip it to rotate. Keep in mind...
