My first microscope finally arrived:

Strange parts review:

It's really nice, even with HD camera. This is a big step up for my home lab

By the way, started my consultanty business, burning the midnight oil since I still have my day job. No customers yet, so if you have a task or hear about one please refer me

The Barlow lenses, to increase working distance, will
set you back another 50 bucks.

Buying the parts individually (HAYEAER), you can sub the
lenses for the camera, if you've already got one, but it
is a pretty confusing search.

Good luck with the business. Good idea to keep the day
job.

Won't increase working distance, the prime focus of the microscope
still has the exact same location. It'll change the magnification, but this is a
stereo microscope with a video pickoff, it'll take a matched triple of
Barlow lenses... a second set of wide-field eyepieces and/or a
bit of digital processing for zoom would make more sense.

It sure SEEMS to be a stereo microscope; binocular objectives are shown in
the pix. I wonder which objective feeds the vidcam?

You'd have to replace the objectives to get a different working distance.

I have the same microscope. Happy with it >> 10 years.
I was always assuming it was Russian, not Chinese. I bought it locally
at Streppel.de, whose main product is fiber optics for €++.

Mine has no camera, only the mounting provision for it. At that time,
they had an interface for Nikon Coolpix only, while I was using Canon.
Now I have a Nikon SLR, but the provided camera is probably the
better deal.

The microscope has a mechanical switch that routes the picture
from the left eyepiece to the camera port.

There is also a lens available to reduce the magnification to 50%.
I don't have it, but it probably makes focusing easier. Full
magnification is usually not needed.

I have a cold light ring source made by Streppel. That has a high rpm
fan that drove me nuts. Now I have replaced it with a Chinese LED
ring light. That's nice but I will change it to DC because it
interferes to my pV amplifiers when they are under the uscope.

I use it for most of my hand soldering. Works fine with the
Metcal ultra fine tip. And a ring light is essential.

I did remove the foot and built a boom that comes from the
rack part of my table where the VNA and scopes are. It is made
from two alu tubes that telescope into each other and can be
swiveled left-right also. Pivot point on the back side of the rack
and a horizontal rail in the front that supports the telescoping
tubes. The vertical arm now hangs top down.
Helps enormously with large boards and it's nice to the VNA and
sampling scope port cables. They can now be as short as possible.

BTW I had absolutely no problem with the links provided.
Nothing to log in etc, just boring.

Cheers, Gerhard

That is really nice, I need to make one. I have very little desk space, so that will be a great build. Can you share a photo by any way?

It's a dual system. So both the eyepices and the video out are active at the same time (some microscopes you need to perform a manual switch between eyepiece and video out)

> You'd have to replace the objectives to get a different working distance.

The actual deal comes with a 0.5x lense, so the working distance is high, allows for a lot of space for soldering iron below the optics
