Help me identify Reichert's objetive and microscope
Best regards to everyone.
I have just acquired a Reichert microscope, but I cannot find any information about this model, if you would be so kind as to give me clarity about this model I would appreciate it very much, also the meaning or what the Reichert S PL 100x objective is specifically designed for.
Thank you very much in advance for your cooperation and we are always in touch through the microhunter forum

Re: Help me identify Reichert's objetive and microscope
I am not familiar with that particular objective, but the stand is a Neopan

Thank you for your kind answer and always good information.
It is possible that the letters S PL are to designate a plan objetive.

Sorry: Not sure about the S
... But Pl almost definitely means Plan

P.S. ... I have the basic binocular version of that ‘scope, and always enjoy using it.
The fine-focus arrangement is unusual, but it works very well.

Re: Help me identify Reichert's objetive and microscope
Yes, sir, very interesting. I just found the following information.
The combined coarse and fine focussing mechanism is ... special: turning the knobs activates the coarse focussing, while the fine focussing is achieved by pushing/pulling the knob bakwards/forwards. It takes some time to get used to it, but it works fine.There's the same set of knobs/dials on both sides of the foot.
The small one(s), on the left in the picture, are used to center the field diaphragm in the FOV by commanding an internal mirror in the foot. The mirror can be seen in the picture below.
The larger, horizontally placed dial(s) are two internal filter wheels.
The vertically placed dial(s), on the right in the picture, are for setting up the illumination. One dial to focus the light source, the other one to open/close the field diaphragm.
...the stage controls are placed at an angle of about 45°, yes. As far as I know there are/were only two microscope manufacturers using this feature on some of their stages: Reichert and PZO (Polskie Zaklady Optyczne = Polisch Optical Industries).

Re: Help me identify Reichert's objetive and microscope
The microscope is actually a Diapan - the big brother of the Neopan - which has the built in illumination system. You can download a brochure (in German) that describes it's features from this website https://www.scribd.com/document/2482846 ... ert-Diapan
The objective is a "semplan" lens (a step between an achromat and a plan lens). The "np" designation indicates that the lens is "strain free" and suitable for use in polarization applications. It can (naturally) also be used for regular brightfield applications.
Cheers

Apologies or my naivety
You are obviously better-informed, John.

Mvmicro.
Thank you for the information and clarification regarding the designation of the S PL. Today I also noticed that this model has a knobs/dials that I cannot find on any other Diapan images that I have looked at on the net, I am curious to know why this knobs/dials is present on this one, but I do not see it on any other Diapan microscope.

Re: Help me identify Reichert's objetive and microscope
. The picture from the underside your microscope reveals a double filter carousel, characteristic of the Fluorvar, although the Fluorvar, which in all other ways is the same as your microscope, has the later coaxial rotary focus, used after about 1975. It is possible that your microscope is in fact a transmitted fluorescence microscope; possibly an earlier Fluorvar or something which might be called a Fluoropan, if such a model existed. I can find no reference to such but the naming pattern would fit Reichert's style. Have you looked to see what the extra knob on the right side does? Possibly a neutral density filter in out control?
Re: Help me identify Reichert's objetive and microscope
Apochronaut.
Interesting.
I'm going to check it out in more detail because I haven't had time yet to spend checking and testing it out. I'm going to do some more research and comment on what that extra knob does.
We already have a new member in the Reichert family. "The fluorpan".

Re: Help me identify Reichert's objetive and microscope
Hello again.
One observation is that the two pictures you have posted seem to be of two different microscopes - the first has the second knob on the base, the other (showing the underside of the scope with additional filter wheel) has the edge of dial protruding from the same area. The latter picture is indeed one of a Fluorpan which looks like the attached picture.
The additional knob on the side of the base as shown in the first picture is a custom modification - it was not produced by Reichert. It would be interesting to learn what it controls.

Re: Help me identify Reichert's objetive and microscope
The full side view picture of the Phasevar , he is using as a reference picture. It's not his scope. It is interesting how similar the 100 watt pan and var microscopes are to the AO 20. The illuminator and base concept are very similar, both with overlapping filter carousels. The 20 had the iris control attached a little more conveniently to a lever on the front but the collimating lens focus was positioned towards the rear, aka Reichert. Reichert , continued to produce the 160mm optical system, which many users of Zetopans loved but slowly introduced 45mm parfocal infinity corrected optics in the Diavar 2( early 70's)) and other of their modernized professional line, while introducing the AO 34mm parfocal infinity optics for the models pitched at the small lab market( late 70's), such as the Neovar 2. For a while they possibly were offering microscopes concurrently with 3 different incompatible optical systems.nvmicro wrote: ↑Tue Jan 21, 2020 6:48 amHello again.
