Re: CAS Reichert Diastar 420 Nomarski DIC

The CAS 200 system was integrated to the Diastar for analysis in cancer research from an OEM. The first generation CAS 100 used a fairly simple modification to the basic microscope. The Cell Analysis System 200 system was the last generation platform from Bacus Laboratories developed before it was s...

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.

Re: Probably dumb question

The Series 160 and 150 objectives were torqued into the nosepiece using an objective wrench to prevent students from stealing or damaging the objective. They were not glued in nor was locktight used.

Re: 50x Oil objective with iris diaphragm intended use?

If a suspect cells was found, switching to the 100x oil could be done and then going back to the 50x scanning lens. Of course a 40x dry could have been used, but usually was con...

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.

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.

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.

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...

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.
