Choosing a Microscope for Electronics & Grain Inspection: Budget 2000 PLN, Durable Option

Good day.
I'm learning electronics, I'll be learning soldering soon, I could use a microscope. Budget is around 2000 PLN, if it's worth it, I can add something more. I'm looking for something that will last a long time. It would also be used to identify diseases of grains, e.g. wheat (to look at it closely).
Regards.

Good day.
For my part, I recommend buying a Soviet-made MBC-9 microscope. It has interchangeable eyepieces that together with the objectives can give a maximum magnification of 100x. The optics are of very good quality. The only thing that needs to be changed is the power supply, because the bulb plug fits perfectly into the mains socket, which gives funny effects and it's not hard to make a mistake. Compared to the microscopes produced by PZO, they are better. Working long hours is also an option. During my work in control, I had the opportunity to practically check the microscopes of various manufacturers and the Soviet ones were of the best quality. There were about 100 microscopes in the plant and they were the most desired by employees. When buying, make sure that there is a set of interchangeable glasses, if not, it's not worth buying.
The microscope has 0.6, 1, 2, 4, 7 objectives and 6,8,12.5,14 x eyepieces. There is also an additional scale for the eyepiece that allows preliminary measurements, the manual gives the value of the scale division depending on the magnification.

I see that their availability is very average, probably drugs are involved, although at the moment there are none :(

There is one such MBC-1 https://sprzedujemy.pl/mbc-1-mikroskop-stereoskopowy-techniczny-strzepcz-2-0010c9-nr58613776

For soldering, you need a microscope with the largest possible distance between the lens and the stage. Also pay attention to the maximum size of tiles that can be viewed

I mean accurate models preferably, you have experience ... based on many things I know that they often write something else and get something else ...

I have a Delta Optical StereoLight microscope, the cheapest of the offer, plastic housing, maximum working distance only 7 cm. I gave 200 PLN. The image quality is very good. Adjustable pupil spacing. Fixed magnification 20x, but it's enough for me. I rarely use it, hence this model. But they offer a lot of models that you can adjust to your needs and budget. They are with and without booms, smooth and constant magnifications. It is possible to rent for testing, although it costs money. Alternatively, ask if you can check the models before buying, in a stationary store.

I move the budget to PLN 3,000, if I buy something, it would be fine ... I am asking for an opinion on these microscopes above ...

Both products and Delta itself as a company/distributor is a failure. Look for other solutions and/or resellers. Take a look at Optek

I think I know you from youtube. From an iPhone for PLN 500, I think your advice is the most reliable ... Thanks

If you want to use a soldering microscope, choose one with a long working distance. You will probably also need a sufficiently high chair to complete the set.
The illuminator is also important.
With a short working distance, it will be difficult to operate the soldering iron. Fumes generated during soldering will settle on the lens and impair visibility. For these reasons, companies make special series of microscopes dedicated to soldering and PCB inspection. One of them is the previously mentioned Discovery L. These microscopes also have a flat table without protruding handles for mounting preparations on a slide and lighting from the bottom.

I understand, this ST6024-B1 has a 100mm working distance, I think it's enough for now and we'll see. I can't see paying PLN 1000 for a tripod...

How do you imagine using a microscope without a tripod?

It has a default tripod, I worded it wrong ... I'm talking about the accessory one, which costs about PLN 1000. The default is 10 cm from the table, it's enough for me.

Added after 5 [minutes]:

And I also have a question if a 10x eyepiece is enough ... it is possible with a 4x lens, 40x magnification and here the question is whether I will need more and thus order more glasses.

I often use a microscope to inspect and solder boards. I don't think I ever needed to change the magnification. But I do raise and lower the microscope almost every time. In my very old one there is a special knob that moves the body in a wide range. The tiles are viewed not only flat but also from different angles. For this reason, the working space is crucial. The model you have chosen does not have an illuminator. Not suitable for PCB in my opinion.
If, as you wrote, you are just learning soldering, why do you want to buy a microscope? This is a specialized tool needed when very small components are used.

Not enough.

For soldering you need 3.5x or even less, for inspection I magnify to 22.5x, more than enough. Of course, I zoom with the knob, without playing with changing lenses.

I recommend this one:

Or if there is access in Poland, then AmScope, it's practically the same.

https://www.elektroda.pl/rtvforum/topic3399981.html

That's right, my final decision ... I buy ST6024 + lighting and accessory glasses to have more room for maneuver. And I will slowly make a tripod myself, I have the means to do so... my father has a workshop, a good migomat, and a lot of junk. Thanks everyone for your help, I'm grateful...

https://techrebal.pl/produkt/mikroskop-stereoskopowy-kamera-do-serwisu-gsm-2/ And yes, it has a zoom ... It seems very good to me ...

The microscope came... Techrebal K10H + 2x lens. The image is super accurate, on the computer from the car you can see chicken and others. I will write something after a longer diagnosis, my beginner's 2 cents. Overall, I recommend it, all metal, well made. Regards.

Not that I'm picking on you, but maybe check first if it even has a substitute for sealing the body, before you recommend it
I will mention the method of mounting the mirrors, the possibility of calibration, etc.

It's clear to me... that you need to use a barlow lens for the microscope for soldering. Anyway, I don't solder enough to worry about it. Lens, e.g. 1x to keep the default parameters and it's cool.

Not that I'm concerned

I also don't want to pick on it, maybe it's good equipment, maybe not, I don't know, but marketers have outdone themselves:

"a microscope can display an image using different displays"
"high resolution optical eyepiece"
"high resolution optical lens"
"wireless"
"electronic magnification is 80-120 multiple continuous adjustments"

They probably translated from Chinese hehe ... but the fact is that through this Optek ST6024 you can only watch flies ...

And could someone briefly and to the point describe the features of the microscope for electronics?. So that you know what to look for when buying.

Well, from what I learned from other forums, it's also like this ... Minimum 100mm working distance, good lighting, and magnification from 15x to 35x. you have to replace the glasses to change the magnification...

if it's only for inspection, it's enough, but why buy 2 microscopes, 1 for work and 2 for inspection?

Amscope and derivatives with 0.5x Barlow have 15cm working distance and 3.5x - 22.5x magnification which is more than enough for soldering and inspection.

Hello
I noticed that you used the Optek szm7045t head with the track switching rod and the Optek st8050t. I am currently using the szm7045t and I am thinking about changing to the latter, and here the question is whether there is a noticeable difference in image quality or is it worth replacing. I mean better brightness at higher magnifications, greater depth of field and generally the quality of the optical path. I will use the camera occasionally.

Can anyone advise me on this topic?

And with this pseudo microscope, you can see the soldering process and the quality of the solders?

Yes, but no regrets
