Yep Don you have got it in one ! What amazes me is that the catch with all of these techniques is clearly visible in the "evidence" - if you can call it that. ...
Hello everyone, my first message to this group. I have ordered an old Leitz Metallux II and supposed to receive it this week. I havent been an enthusiast, but...
Bob, You can use an objective that has a higher NA than 0.80 but you won't get darkfield. You'll have some light entering the objective directly giving you...
Hi Just noticed the BBC News website highlighting this optical microscope development reported in Nature in case of interest. 'Tiny glass beads' are used. ...
The evanescent waves aspect basically relates to diffraction limits not applying over sub wave length distances. That definition came out of a weighty tomb on...
John, the far field lens means that the lens is at the sample surface. hence the term far field. The very small spheres (2 micron diameter) collect an image...
Thanks Mike. To me it's confusing as the spheres are in contact so are capturing evanescent waves. That's the only way it can offer better resolution. I...
Hi Randall, The feature article on Resolving Diatom Shell Structures is not up anymore. If you downloaded a copy is it possible to email me a copy? Thanks. ...
Leitz produced a wide variety of microscope models and many different parts for them, some of which can be interchanged while some cannot. You might look...
Hi Jake, Sorry, I don't have a copy BUT, just Google Microscopy Today. Click on the "Archives" box, left center. The article on Diatoms is featured in Vol...
I have a Laborlux from the sixties and a Kavar camera adapter, both of which are new to me. I need to purchase or fabricate the adapter that fits between the...
All, I have a scope on which some idiot used an electric engraver to engrave the name of the college onto the arm of the scope. Does anyone have any ideas on...
If it were done in a profesional manner then I would not be too concerned. Unfortunately the poor execution reduces the value of the scope and detracts from...
Thanks Randall and David for your responses. I found it. Take care, Jake From: Microscope@yahoogroups.com [mailto:Microscope@yahoogroups.com] On Behalf Of...
Hi John, it's my understanding that the coating of spheres would be the only device between the lens of the objective and the sample thus no oil is present. It...
Hi Mike. A misunderstanding I think. I mentioned oil because of the claimed max resolution of 50nm. The popsci article shows true 100nm resolution and I would...
You could consider replacing the engraved part? Often bare stands or instruments with worn, damaged or corroded parts can be purchased quite cheaply on Ebay or...
Bill. There are automotive fillers about that are much easier to sand down than normal epoxy fillers. You should find suitable fillers in many motor factors....
I feel your pain in this. Just from the sheer reality that destroying the finish by engraving could have exposed the metal to oxidation and further erosion by...
"Previously, the standard optical microscope could only see items around one micrometer — 0.001 millimeters — clearly. But now, by combining an optical...
I don't think anyone with skill in the use of the air brush and paint colour mixing would have any problems matching a black German scope. Textured finishes...
