Hello TMT, The CK is indeed a rugged old lab grade inverted tissue and cell culture scope. Not a research platform, but simple, well designed, and many were...
Gordon, I would expect that they are indeed brand specific - but that doesn't necessarily mean that similar glass cannot be purchased outside of the...
Thanks for responding.... One of the reasons why I ask about the phase capabilty is to determine whether the more recent CK2 accessories would work on a CK ...
Sure, Not sure about the CK2 accessories on an old CK - would require some modification, if not more. I believe the CK used the short barrel objectives, the...
After reading various threads in this group I purchased a used Nikon Coolpix 5000. I finally found the free time to mount it on my microscope and test it....
I have exposed several hundred images using a Coolpix 5000 with several scopes and have never encountered the circular rings you mentioned. Gerald Sheine In a...
I recently acquired a Canon S3 IS still camera with movie mode and am in the beginnings of documenting the microbial life in my water barrel. To my pleasant...
... Very neat! I can't offer much in the way of constructive criticism in the sense that I don't know what a lot of biolgical specimens are supposed to look ...
Excellent Thomas, Great lighting, focus and color. Very well done! Dan ... From: Thomas Ashcraft <ashcraft@...> To: Microscope@yahoogroups.com Sent:...
Try zooming in a lot on a light back ground with good ligthing. That will bring it out if anything will. I have seen rings in images I took in side by side...
Does anyone know what the optical element in the nosepiece of my ortholux 1 does. If I remove it, the scope does not focus correctly. Is there a situation...
They look like Newton rings. Your experiment with a phototube with no eyepiece hints that they are not coming from a lens being too close to the eyepiece. Is...
Thanks to all for the comments. Great article Gordon. I am still looking for the source of the rings. I eliminated several sources by removing my Optivar...
Just an observation: AO Series 2 and 4 scopes -- 160mm T.L., late 190's, -also have- an optical element in the nosepiece. Earlier scopes -- Series 35/15 or...
Here are two articles addressing ring artifacts: http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artdec03/pjimaging.html ...
... Hi, Sounds like you are talking about the intermediate tube lens for the Ortholux (there was no Ortholux I). In all honesty, you found out what it does: it...
Thank you for the links. The Henkel artical is especially informative and saved me a great deal of time. I will just accept the artifacts are there and use...
Hi Steve, I might add that typically I have also found that the same techniques mentioned by Ted Clarke and others whereby you minimize the aperture (opening...
Hi Steve, I will make a large bet its the camera lens. The image is in focus as it comes from the eyepiece. If you tack a piece of enlarging paper to the ...
Norm, The physical and optical tube length on an Otholux one is a great deal longer than 170 mm. The lens corrects for it. There is also a tube lens for ...
Group, Does anyone know of any older microscope models that had built in flash? It seems lots of us are jumping through hoops trying to get electronic flash...
Were there any dedicated photo eyepieces for the Leitz ortholux series of objectives. I read somewhere that the Leitz 2.5x projection eyepiece should not be...
Hello Gordon, I have been able to adjust out the rings when I followed the advice I was given. I posted a few jpgs. However, I clearly have much work to do....
The Leitz Periplans are recommended for the Wild/Leitz MPS series of cameras. I have two Wild tubes, one for compound microscopes marked: Leitz Periplan GF...
Hi Norm, Projection eyepieces work best when projection the image onto film or a CCD. To get the right size on a digital camera a 2.5x eyepiece has too much ...
Just a quick post to say that I use the Coolpix 5000 and was experiencing those ring artifacts at oil immersion magnification when using the cheap relay lens...
I think wild had a lighting unit that had a flash slider that slid in the light path. Gordon ... [Non-text portions of this message have been removed]...
