I am searching this part for my AxioLab RE 450905

"Binocular phototube 35 ° / 20 (with switching 100% light for observation or 100% for camera)
Order part no .: 452909

Thanks

Hi folks, me again writing. Time ago I asked assistance from Zeiss about the trinocular for my AxioLab Re and today they have unfortunately confirmed that trinoculars pn 452910 and 452914 would not fit my scope as they are for Axioscops not Axiolabs. The trinocular that would fit is 452909 but I can...

What would you pick ? The dovetail connectors of the three heads appear to be the same, or very similar to each other, and differ from the connector on the head of your present binocular. So, a dilema. Hopefully an expert on Zeiss Axio will join and judge. Or I would continue to investigate in Zeis...

In all three of these images, I found the farthest away point that was in focus (in the depth of field), made note of that; then I found the closest in-focus point in the depth of field and made note of that. I started with the former and worked toward the latter in tiny increments: making a "captu...

Do you have a pic or link for specs ?

Sorry to disturb you again, just an update. I dismantled the binocular head of my the Axioscope RE to check the dimensions of the mechanical parts and happy to read the manufct. code being 452908. Hence it is quite risk-free that the three trinocular currently on sale - the 452914, 452902 and the 45...

[/quote]Sorry, magnification is (at least in practice) the same with / without oil.[/quote] Hobbyst, I confirm your statement, i checked without oil. The Carl Zeiss x100 code 4860960 (1.30 na) objective is actually x850 (kinda a false marketing lol!). I bought this Zeiss second hand but after I clea...

I approach it differently. Irrespective of the scale of the reticle. On my PC screen, with the 63X objective, 150um = 19.5cm. And with the 100X objective, 120um = 19.5cm. Hence, the apparent ratio of FOVs between them is 150/120=1.25. If the images were obtained under identical conditions , the rat...

I did all this already and I knew all the theory

Sorry !

MichaelG.

You dont need to apologize, it is ok and thanks for your time

in the x63 obj. 95 reticle units measured 150um, hence 1 unit - 150/95 = 1.58um/div actual magnification: 950um (reticle units) / 15um (actual) = x 63.3 in the x100 obj., 95 reticle units measured 110um, hence 1 unit - 110/95 = 1.17um/div magn 1000/1.17 = x854 (not x 1000) actual magnification: 950u...

I did all this already and I knew all the theory, but my question was that when I calibrated the oil immersion x100, the distance between the 10um grades of the reticle where 11.74um and hence asking what is the actually magnification x100 or x 85 or x117 under oil immersion ?

I want to be sure that what I am doing/assuming is correct. I need to measure some spores and assume I am using the x100 objective (oil) with the eyepiece of x10 and a reticle with 10 um (0.01mm) per division. The theoretic distance between each division is 1um. However when use a stage micrometre w...

I am attaching a related page from a dated Zeiss Manual which should be helpful a bit more over the good replies you got

Thank you, I am digesting the info you kindly provided in the last posts!!

Here is the pdf for other users who in the future have my issues:

So this part ZEISS Trinocular Microscope Head For Axio Series 45 29 14 has a code different from mine series 45 09 05. Does it still match? By sight, it looks similar to mine. I am also concerned that the phototube is so wide! Is it a standard size like that or something alien nowadays?

Better a canceled transaction and refund than a very risky purchase, with the headache of returning broken parts. Especially since the seller does not accept returns. the scope might have been lying in this condition for a long period in a storage yard. Here is a maybe much better option ? https://...

...Did you see this and what u think please? - https://www.ebay.com/itm/Zeiss-Axiolab-RE-Microscope-/123948436636 It is configured for epi-fluorescence. Will be useful for general epi-illumination, if the top (external) illuminator is replaced. That illuminator (on the top back of the scope) is a h...

Thnks kirby, as I see it is some special degreaser, like we have here under a variety of names such as Sgrassatore.
Thanks!

I found an online shop in Europe (Switzerland) which sells home and ironmongery stuff, amongst which was an original bulb for Zeiss microscopes (25W / 6V) at around 20Eur. My previous searches on ebay were from US at 40-50Eur plus shipping plus taxes. I am not sure if Eu countries have to pay Vat fr...

Thank you for your help guys Here is a quick contribution by smartphone / Canon Gx5 digital camera over the eyepiece to show my appreciation for your help. The canon has dust in its barrel that is not seen in everyday photos but terrifying when taking photos from the lens. When I had the other micro...

I am restoring my 2-year neglected Carl Zeiss AxioLab and so far i had good success. Here is an image of the asci and its 8 spores of Otidea leporina. Many thanks to the guys in the microscope & optics section (not sure if they are here too!) First two pics from S10 Samsung over eyepiece Last one fr...

I skimmed and read parts of your long, well researched and exhaustive article. Well done and I was impressed by the effort and dedication and passion it involved. Also a huge thanks for putting this sterling work online. The accompanying pics (all captioned and credited) were wonderful. I kinda hope...

They are not bacteria (at x40 you would see them as dots) and the chaining suggests living matter. It must be a microfungus, and I don't know if it may be the yeast Candida albicans (that found in female pouches!)

Then it is all about guts feeling!!!
The bad news is that there isn't much selling what i want! Today there is this 'deal' tomorrow and after tomorrow might be none

Update; when I asked the seller (from Israel) what is the fault and if the head is fine, he replied "I just dont know"... raising the risk level quite high. The pics show a fine well treated scope... hmmm!

While I dont want to interfere with the recent discussion, I just wanted to update u that I bought the 1. ZEISS Plan NeoFluar 100x Oil Objective for 415Eur (plus shipping). Now I realised that I might have to pay taxes although it may pass as educational or medical.

Hi 75RR, thanks for your comments, very valuable of course. Yes the x1000 magnification is important in mycology, 1 for seeing detail in the surface (coat) of spores and then 2. for measurements, were measuring spores on a reticule at x1000 is more accurate than at x40 (average length of spores is 8...

You will not be pleased with the performance of the A-Plan ph 3. Phase objectives, when used for bright field , are affected by a small degree of spherical aberration due to the presence of the phase plate in the objective. It is noticeable with all objectives to some degree but lower power objecti...
