Re: Affordable microscope bulb for Zeiss

Just out of curiosity ... Does anyone understand why the Axiolab lamp is listed as 25W when the actual bulb illustrated is clearly marked 30W :?: https://www.itvinas.com/replacement-bulb-for-carl-zeiss-axiolab-halogen-axiolab-a-axiotech-25-25w-6v-p-503486.htm MichaelG. Remember it is a fake site

Do you have the Zeiss designation for it?

Yes and I can solder too, but the rating is 6V 25W while that store only sells 6V 20W Osram. Any other option please?

Re: Advice new or refurbish my Zeiss?

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...

Re: Advice new or refurbish my Zeiss?

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.

Re: Advice new or refurbish my Zeiss?

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...

Re: Magnification of oil immersion

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...

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...

Re: Magnification of oil immersion

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 ?

Magnification of 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...

Re: Advice new or refurbish my Zeiss?

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?
