Hi Asif, etal, I measured the phase annuli as best as I could without taking the turret apart and here is what I came up with; #1 ring inside diameter = 3.25...
Hello Stan, Typically, the smaller the ring, the higher the magnification. Sorry I can't offer much more definitive assist on this one. Match the largest...
Harry: Thanks for the report. I once lived in Jackson for three years -- in a "fashionable old downtown" neighborhoods just across the street and up two house...
Hi, Sandy, and others, Yep, Sandy, you pegged it! I knew Miss Welty from the time I was fifteen, and lived around the corner from her for 30 years or so, ...
We in the Southwest would not expect to have much in the way of fallout from Katrina, but the area hospitals have now been given a heads-up to expect refugees...
Hello, all, The images of human suffering from New Orleans and the Coast are at last not nearly so grim, and the successful completion of the major ...
Gregg & Stan, isn't this backwards? ... Sorry I can't offer much more definitive assist on this one. Match the largest ring to your lowest power objective,...
Thinking about my unaccustomed outburst of optimism in re the hurricane recovery situation in my next to last post, I certainly didn't wish to compare the...
Harry and Gregg, Yes, I think you are right, Harry. But since it was only last night, that I found out that if I move the condenser up and down, there is a ...
OK, Stan, I'm going to try a walk-through. First, let's go to the 10X objective. We'll assume that your smallest ring is the one to match it. Put a slide on....
You may be correct, Harry - I am working from (ancient) memory as I have no phase equipment here to refer to. My apologies, Stan - I wasn't trying to mislead...
Harry, What you have isn't news. The system was working fine working its way into New Orleans. Getting things cleaned up and working in 4 days is pretty good...
Hey, no problem, Gregg! At least you guys got me interested in phase again, and that's going to lead me to finish building a Koehler illuminator from some old...
Harry, Boxs, cross, bars and stars well as ring and probably a lot of shapes that haven been tried will work for Zernike phase images in scales other than...
Yes, Gordon, I've seen the cross configurations in books. Actually, I'm kind of surprised that the "stars and bars" configurations aren't more popular down...
Hi All, I want to address off topic posts. My first description of the group was, a group of acquaintances sitting around the living room discussing microscopy...
All this phase stuff made me remember several years ago I came across a website where a chap described what he called "poor man's phase" or something like that...
Hi Harry, Thanks, This was just what I needed, and with your help it proved successful. (I think) Please check out the pictures and let me know. I have posted...
They look great, Stan, Glad to know that the rings and objectives were made for each other! Now you can play around some more with illumination, etc. and see...
Stan, I pretty well agree with you, but I will try to not abuse that and keep most messages on topic. I have a microscopy question- I was recently sent back...
Dave, I'm going to throw in another 2 cents worth, but bear in mind that I've never been faced with intensive diatom cleaning and some of this is book stuff,...
Harry, ... Now all I have to do is to figure out what the forth annuli is for. It is about the same as number one but is a thinner ring. ... Thanks for the...
Dave, The only thing I can add to what Harry said, is the jewelry cleaner you buy for a buck or more for a little jar, is just a diluted sudsy ammonia, which...
Stan, usually those 600 series condensers are set up with the #1 slot for the 10x, #2 for the 40x and #3 for the 100x with the #4 being a very large ring for...
Hello Harry, Your post reminded me of what was once a common accessory on the finest metallographs made a half-century back. It was a "lollipop" type insert...
Arthur, This is a copy of an earlier email I posted with the condenser info; I measured the phase annuli as best as I could without taking the turret apart and...
Hi All, I, as usual have a few questions, and as usual am looking to the group for answers. Immersion oil; I have just tried out the B&L oil contact cardioid /...
Hi Stan - water should work well - give it a try. All the best, Ron ... From: Stan Muller To: microscopehobby@yahoogroups.com Sent: Monday, September 05, 2005...
Stan, Water and glercine work but oil that has the same index of refraction of the glass is great deal better an 15 or 20 dollars worth last a very long time....
