Peter, I have found that when photographing at high magnification is when I have to be sure I've got that diaphram set correctly. It makes the photos noticable...

Hello All, My 100X objective seems to be dirty. It was clear when I first got the microscope, but I have looked at a lot of pond water and the objective lens...
Hi, I posed a similar question a while ago concerning using the 2.5x objective on a Zeiss Standard 'scope. It was suggested that I take the condenser out...
I am really not qualified to give you an advise, but I can tell you of my own experience. I recently bought a Labomed CMZ-4 stereo zoom microscope. This is...

Hi there, Carol, Don't take the objective apart, that would almost certainly make things much worse. I suggest that you put it back on the microscope to keep...
I am not in a position to give an advise, but this might happen to me as well. Are there any issues in using the square cleaning (microfiber) cloth just about...
... I was under the impression that the lower phase annulus was the "equivalent" of the condenser diaphragm, so one still needed to control the incident light...
... As far as I know, with phase contrast or conoscopic illumination, you want the effects that are provided by having light enter the objective at an angle. I...
Hi there, I've seen microfibre cloths advertised but I have no personal experience of them. I'll defer to other more experienced members of the group on that...

Hi, Take a look at Ebay item 160246529286. It is a Zeiss 1.6x - 5x zoom objective (Na 0.03 - 0.1) for 160 mm stands (part number 4619572). I have no intention...
MY COMMENTS and ADVISE Is there any confidence in the new Chinese stereo microscopes or what are your opinions on them? --> NO CONFIDENCE, at least none for...
First off, the pic stinks. Second, I doubt it will fit most stands, because of its length. I wonder if the 160 mm tube length is marked on the unit or is a...
