Thank you again all - really thoughtful and comprehensive input. I may be able to buy a Nikon SMZ645 for $250-300 or so. I wonder what you all think about that opportunity. This would come with what

I personally wear bifocals. I take them off when using the microscope, to allow my eyes to get close enough to see the full field of view. It just shift the optimum focus for me, from what's optimum

From my long ago youth futzing around in a tool and die shop, I recall, there is also a (rarely found) 5-40 ANSI thread Sure

If the unit is English then the screws are 4-40, 6-32, and 8-32. If the unit is metric then the screws are 2.5 mm, 3.5 mm, and 4.0 mm

Hi Ulf, Thanks for the disks. If you find other similar disks please upload them to the group files section. 73, Razvan

It's interesting to read the various posts. I possess both video microscopes and binocular styles as well depending upon the work being done. Out of all I usually grab a video unit first off.

I do not recommend the digital microscopes, because they don't provide stereo vision, which is really important when working on SMT components. I've been using stereo microscopes for at least 20

Radu, I'm a little late jumping in, but here goes. I have a couple of issues that impact my bench work. First is that I have vision problems and need magnification to do even basic work. Second is

Thank you all, great input. From these choices, it sounds like a stereo microscope on a boom would be ideal. I do tend to work on all sorts of positions and oftentimes spill outside of the desk/bench.

Maybe I have the same problem as the 8656: the cover screws for the 8643 is NOT 6-32 (USA, national coarse), nor is it 6-40 (USA, national fine). The diameter is very close to USA #6, a finer thread

I went to a hardware specialty store with one of the Torx screws from the 8643. They said it was not a metric diameter. Nor was it 32 threads per inch, a US "coarse" thread. They said it look like it

Thanks. I had some free time today and experimented with a discretely designed gain block in place of the MMIC. I think I'm hitting the limits of the E5052A now but I managed -170dBc/Hz at 10kHz

Hello Ulf, The HP "ASCII" files can be converted to a Windows txt form with HPDIR. I wrote some time ago a small Windows utility that is doing this, also in batch mode (multiple files at once). I

This is a common failure point on these.? Simply removing and reinstalling the connector to the backplane board on mine returned it to specified voltage.? I then cleaned it with denatured alcohol

If you do consider getting a stereo microscope then I'd recommend something with prism lenses as this allows a more natural viewing angle. This does come at some expense of optical quality compared to

In the case of the Mantis, I would recommend to 'try before you buy' as the Mantis doesn't suit everyone. At work opinions are divided, some people avoid using the Mantis as they get distorted vision

The Mantis by Vision Engineering. On the prototyping bench I moved from a Nikon SMZ-1 with an after-market LED ring light to a 1st-generation Mantis about ten years ago, and upgraded to a Mantis

If you have an opportunity, check out a Mantis. Sometimes you can find good deals on used ones. They are absolutely amazing - a binocular scope without eyepieces. There's been a lot of writeup on
