Re: Eyepieces Zeiss.
Hi Sabatini, what you have there are Leitz (160 or 170mm)and Zeiss Jena 160mm microcopes. For the Leitz microscope you need Leitz Periplan eyepieces as they contain a certain degree of colour correction. With Zeiss Jena it is a bit more difficult. Your objectives will be on one of the last 160mm se...

Re: Eyepieces Zeiss.
They're 22mm. In this case you think is a good choice.?Phill Brown wrote: ↑Mon Apr 18, 2022 6:55 pmThey look like 30mm which might not be ok.
23.2mm is more likely what you have?

Eyepieces Zeiss.
Cordial greetings. Here I come again looking help of those here always willing to expand our knowledge. These zeiss eyepieces which I show below are from Zeiss, I think primostar infinite system. The thing is that my microscopes are all 160 and 170 mm.... Both Zeiss and laitz. The question I have is...

By recommendation of Hobbyst46...sr, I couldn't see them with epifluorescence...so I will still be able to show them in Bright field.

Re: Introducción to a Laborlux D epifluorescencia.
The I2/3 is for blue light excitation in a band of 450 - 490 nm. Very good for specific fluorescence stains but somewhat limited on chlorophyl auto-fluorescence. A blue LED in the 460 - 470 nm range would be best for this filter cube. Buy some acridine orange. It is the perfect stain for this filte...

Re: Introducción to a Laborlux D epifluorescencia.
The 2.5/0.08 is a central part of your problem. This objective is totally useless for fluorescence. Use your Fluotars. They are much better suited to the job. What filter cubes do you have and which one did you use? btw: Nice microscope! This thing will give you a lot of pleasure and reward. Thank ...

Re: Introducción to a Laborlux D epifluorescencia.
Incidentally : Do the posted photos show that the light from the 100W LED comes from below the light port below the condenser ? if so, the setup is not epi-fluorescence but trans-illumination. If so, the chance of seeing any FL in the shown setup is zero, whatever the objective in use, whatever the...

Introducción to a Laborlux D epifluorescencia.
Kind regards to all. As we all know in this beautiful world of microscopes, our mind is always searching for better optical quality and this keeps us in the search and expectation of finding and obtaining better optics. Now in this search, I managed to buy two nice microscopes a laborlux S and a lab...

Re: Leítz 25x EF. Possibly re-cemented.
The front element is sealed into it's mount or bezel, often by furling an interior section of it over the extreme edge of the front element's rear hemisphere. The amount of metal is very thin and undue pressure on the front lens can push it through the furled ring. Cementing the lens with epoxy is ...

Cordial greetings . I just purchased this leitz 25 x EF, it's giving a clear and contrasted images, I was cleaning it and noticed that it has some leftover glue like possibly Canada balsam by the color on the front element. But I wonder if it is possibly it has been recementing the front element or ...

Use a measured slide as a coverslip. There are also thick coverslips used for haemocytometers , usually .4 but I think there are thicker ones as well.

Does anyone have a solution for using this objective on a non-inverted microscope?
