Hi David, I never made stereo pairs with the SEM because we where not involved in that but I see no problem. The stage is easily controlled. It would be fun to...
Hello Hans & Peter, Thank you very much for making your outstanding images available to us! Although the group's primary interest is optical microscopy, it's...
Hi all, It is always difficult to image non-conducting samples in a SEM but a low voltage and a low current and fast scanning can help a lot. The diatoms are...
The bulb you have is a GE 1630. Rated at 6.5 volts, 2.77 amp, 18 watts. More info here: http://www.servicelighting.com/catalog_product.cfm?prod=EK40311 The AO...
Compelled to reply to this thread ... I'm glad to see the MBA crisis pointed out (once again). Unfortunately, it's not the only problem. One has to point out...
Hi Hans & the Group, I'll take a shot at organizing the Ap sample from Klauss Kemp - but no guarantees as to how long this will take! In the meantime, I found...
Ok it's easy from the second image: the pore in 10 micron are about 65 (separation about 0.15 micron). The striae in typlical Amphipleura are 39 in 10 micron...
Maurice What does an AO 359 look like? Can you point me to a picture of it? I just bought an AO Model 370 illuminator (shipped to me today), and am scouring...
Alessandro, Having measured the 5 micron bar on Rene's SEM plot, and knowing that the bar at this magnification on a Cambridge Instruments SEM is pretty...
An MBA has nothing to do with crappy scopes. It is an education. It has also nothing to do with greed. Greed is a feature that I can find too often in us. So,...
Calling your attention to possible corrections for the new home page photo: Spelling should be ..ostracod I believe we are viewing the dead shell (valve)...
Gregor, I wish that it was only rumours we had to worry about. Generally, it is not optical quality that is the issue, it is mechanical. If you look at the...
Hi, I remember stria separation with one Leitz NPL Fluotar 50X/1.00 oil with Zeiss DIC but obviously without oblique light on K. Kemp test plate and this is...
Hello, Merv: I am not debating that especially the mechanical performance of many microscopes was better in the past. I appreciate my good old Ortholux every...
Hi Merv, While I couldn't agree more that the arguement is bizzare, it is unfortunetly accurate in many cases. Adding insult to injury though is the fact that...
Dear Gregor: You are out of line. Discussing the "MBA mentality" was cogent to the discussion thread, and it is a business/cultural phenomenon that has been...
All, First, congratulations to Merv (and Hev?) on a brilliant story. It seems to me that there are several intersecting problems here. In the years when...
I can assure you that your issues with replacing your HW in your classroom have absolutely nothing to do with the quality of new Nikon, Zeiss, Olympus and/or...
Hi Steve, An item, advertised as a 359, is listed on ebay 280064096257. I think that this unit is "prefocused" and does not have an iris. Best, Jim ... am...
Ok, I have seen both Series 10 and 20 scope and there is no lens in the frame above the objective turret. These models are two of the original (or at least,...
Dear Jim: For all the external Koehler set ups which I have seen, the external illuminator has a focusable field condenser lens and a built in field iris. What...
Jim I found what I think is the instruction sheet for your illuminator Steve Born StevenBorn@...  ... [Non-text portions of this message have been...
Dr. Hirwan, I don't think that Tasco scopes are thought too highly of, and for that reason, I am guessing that many in this group would suggest buying a new...
Jim It occurred to me that square Cokin filters (3"x3" or 4"x4") for professional photographers could be adapted to the AO 370 and AO 735 illuminators. They...
Hi Jim, An AO Series 2 or 4 with a monocular head has no lens at the top of the frame - because the physical tube length is 160mm. Stands made for the...
