Re: A.O. dark/phase objectives wanted

Just missed. I have a complete 1205 PP4 kit. With condenser, aperture viewing unit and turret condenser for the Microstar IV and all 4 objective. In new condition.

Re: Reichert 410 "Microstar IV" head -- corrective element present in binocular path but not trinocular camera port

Hans, Do you have access to the 1762Y 2.8x adapter or the 1763Y 5x adapter from the PhotoStar camera system. These are equipped with a Tmount for the Konica SLR. It might be interesting to engineer a Nikon Tmount in it place. Then your DSLR could be mounted directly to the trinoc with optics that sh...

Re: WTB ready-to-use ~$400 used microscope from forum member

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...

Re: Why are binocular eye tubes angled inward slightly?

As far as I remember, the converging eyetubes from the A0 through Leica infinity series compound microscopes was unique to that brand. Although it would seem logical to assume that it would replicate a stereo effect, that is not the case. The philosophy from the designers was that the image being vi...

Re: Reichert Austria WP 10x/20 eyepieces -- what microscope were they designed for?

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.

Re: Reichert Austria WP 10x/20 eyepieces -- what microscope were they designed for?

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...

The two adjustable eye tubes are for use on dual and multi view microscope systems so the secondary users can adjust each eye for acuity differences from the main user.

This is one of the Semiconductor workstations that was built off the Ergoplan microscope platform. Depend on the timing, it could be called a IMS 2000. The Leica Semiconductor Equipment Group was divested to Vistec in the mid 2000's about the time Danaher became the buyer of Leica Microsystems.

Good discussion from all. To answer the original question, the Series 100 and Series 110 were essentially the same microscope.
