Stereomicroscope

What does it look like?
What's wrong with MBS-10 (http://www.lzos.ru/microscope.htm)?

About MS-2 here, for example:
http://www.veber.ru/podrob.php?tovar=31&to...d46da20ba95bbf8
What makes MBS-10 better than the rest?

Just me MBS-10 as it is more familiar, about MS-2 for the first time I hear

MBS-10, perhaps, also at a better price, well, and a domestic manufacturer-patriotizm, so to speak

I also figured out that if it (MS-2) has a price comparable to MBS-10, then minus customs clearance and seller's cheating, the purchase price seems very small... Zeis and other Watering cans are somehow used to operating with numbers in Yandex units with three zeros
I don't know, but something is confusing me

I understand that the MS (stereoscopic microscope) is a domestic binocular manufactured by LOMO in St. Petersburg. Therefore, the price is normal. But the fact that you need to use attachments for maximum magnifications is not good. I don't know how to explain it correctly, but using this for MBS did not lead to anything good, everything is very distorted and the depth of field is so small that only a small part of the object is visible.
There is another device of ours - the MSPE-1 binocular stereo pancratic microscope.
http://mikroskop.by.ru/mikroskop-mspe-1.htm this page has a terrible picture, but the characteristics are not bad.

Apparently, the MS-2 is really a Lomov device, in any case, it looks our way. The main magnification is achieved by the lens itself (...20x) and eyepieces (1-4x), i.e. 80 maximum without attachments. The nozzles are essentially used to change the working distance, which is about 85 mm for the MS-2 (10 less than for the MBS-10). The price in the store is about 13 900, and taking into account the ring illuminator, eyepieces, etc. - approximately 17 000.

And on the link they write that they are being taken from the "FRG"...
Or is it about binoculars?

Oh, I won't lie - I just don't know for sure.

it looks like a simple UNICO model , but the price is really Russian. I hope the optics aren't plastic."

This page contains excellent illustrations with the technical characteristics of most modern binoculars, the eyes run away...

Colleagues, tell me, plz.
There is a desire to purchase a new microscope. Of the available ones, I only noticed the MS-2 (in St. Petersburg, "Observation devices"). Has anyone used this device?

I think I figured out what kind of company it is: binoculars MC. These are Chinese copies of Japanese Meiji stereo microscopes. And I must say the copies are excellent! I went to the office that sells them (and they themselves are not aware of their origin) and carefully poyuzal device. The result is a purchase. The quality is excellent, the day before I sat for a long time with a watering can in the laboratory and the eye remembered the beauty well. So, there are no differences, but the price... you know that.
So the end of the MBS era has come.

Then I have questions as a user:)
What kind of lights did you buy for it (I'm interested in ring lights)? From the links, I found this:
Fiber illuminator - fiber illuminator unit (for MS) +
Fiber ring illuminator (for MS)
Or here is such an aggregate:
Ring illuminator for microscopes of the MS series, MBS

Prices differ markedly. As for the second one, I am impressed by the fact that I already have an MBS-10 and the" native " lighting unit and CVO for it are bulky and expensive...

Fiber costs almost like a microscope:) When I was looking, I noticed the ring daylight - the price is about 500 that whether re.

So you bought it? If so, can you tell me what the diameter of the inner ring is?
The price for it according to the link that I gave is 1630 rubles., Did you buy the same company (if you bought it)?

I haven't bought it yet. I can't say the exact dimeter, but the illuminator is attached to the lens with three screws, i.e. it is quite versatile. The price, of course, in the previous post lied. The price in the store is 1050-without adjustment, 1680 - with it. A ring fiber-as much as 9150.

The diameter of the inner ring of a simple ring illuminator (with a halogen tube) is also suitable for MBS. Another thing is why it is needed? Now we sell excellent table lamps with powerful tubes (11w) The main thing is that the light source is not from one point, you need a tube. And shadowless lighting is a fiction, there will be bad shadows. In general, shadows are a useful thing, the volume and sculpture are perfectly visible.
Fiber ring illuminator is very expensive, 9 thousand and do not forget about the block to it 6.500 thousand
This thing is only needed to work with very small objects 1-3 mm and at maximum magnifications of 80-100 times. In addition, insects desperately glare from such bright sources and the sight is depressing...
Another thing is that when using the appropriate paper filters, fiber illuminators (conventional and to a lesser extent ring) are perfectly suitable for photographing, and for shooting small objects they are simply irreplaceable.

I know about lamps with a tube, at work it's like this

What kind of illuminator with a microscope did you buy?
I just had a problem, the regular MBS-10 illuminator died, and I frantically and thoughtfully select a new one.
Small objects have to be viewed, for example, ground beetles of R. Bembidion, their average size is 4-5 mm, and structures that are important in determining them are correspondingly even smaller.
I looked today in the Zeiss binocular, it really has a fiber illuminator with a light filter, such a smoky one.

Do you have any photos of the same insect, under the illumination of a ring illuminator and a lamp with a tube?

1) Look again at the photo and accept my suggestions: such lamps are sold in any place where there are lamps, especially Philips.. isn't it easier for a small price to buy and come up with the rest for fixing yourself!? It will be much cheaper. And you're not Americans, either, so you won't have to guess

2) Does this mean an ms - something microscope costs about $ 90 new?? Like his 7-fold magnification, for example, ex. is it less visible and blurry? And then at our Institute, almost all binoculars, starting with 4-ktr, so darken the image that you have to use a maximum of 2 lenses. But there is 1 binocular, as with 4, and it seems even at 7x displays a normal picture. Maybe these are old lenses? In general, the final question: with different magnifications, the picture is the same, or are there changes?

3) The Americans have seen somewhere-a hundred-something like an illuminator in the photo, only in the middle of a large lens (magnifying glass), everything is held on a flexible and rotating leg, it seems very easy to work with such a device, you don't need to poke your eye into the tube forever.. Do we have them? I would like such a thing home..

I checked yesterday with an 11W table halogen lamp with a tube - the result is better than from a regular illuminator, no doubt. I'll try to find the same ring lamp and try it again.

1) I'm leaning towards this option, the only thing that bothers me is that I myself will not be able to build a device for a smooth change in brightness.
2) It depends on the quality of the optics, my MBS-10 is also dark already on 4x, and on 7x there is also blurring almost throughout the entire field of vision, except for the middle section (the binocular is old, it was already written off ).
3) This thing is popular in movies, no film forensic laboratory can do without it I think that its usefulness is greatly exaggerated

It depends on the quality of the optics, my MBS-10 is also dark already at 4x, and at 7x there is also blurring almost across the entire field of view.

Do not suffer and take an 11w lamp, which works perfectly with any objects.
I think that the darkness at high magnifications in MBS is also associated with a poor standard illuminator. at one time, I immediately abandoned it and switched to table lamps.
The advantage of a halogen tube is that it heats up slightly and can be moved very close to the object, providing a perfect uniform diffused illumination

"Soiling" of optics is most likely from dirt accumulated on the prisms of the binocular, if the lenses can still be cleaned somehow, then the prisms are very difficult, because it is usually not possible to assemble the structure well after disassembly and cleaning.

I have such a question: what is the lamp in this ring illuminator? Could you (if it is not difficult) find out its marking? And then I ask in stores about the "lamp in the form of a ring", but so far to no avail. I found something similar at Philips (TL-E and TL5 series lamps), but I didn't see them live (and judging by the description- "tube diameter 26 mm" is a little different).

lamps in such binoculars MA305 / 100 (110V) or MA305 / 200 (220 / 240V) see the photo
, but we probably can't get them...

By the way, exactly the same binoculars as MS, but already under the Meiji label, cost as much as $ 1700-2000, and not$ 600 as in Russia. At the same time, this is the maximum configuration!
If anyone doesn't believe me compare it http://veber.ru/catalog/1/10/page/3 and

I'll try to look

As for MS-2.
Call Veber and ask for a wholesale discount - they will immediately give you 30%, and from the volume up to 45%.+ their considerable profit of 20-40% + correctly noticed above customs clearance and delivery. The price at home in China is about 100-150 uy.
On MBS-10, which, by the way, also sells discounts, you do not need them.

A friend of mine sells biological microscopes from China - a 30% return, but at the expense of a good profit, it pays off well. Basically, the mechanics fly - there is always a detail that the Chinese will copy from the shit.

The Chinese have long put on the shoulder blades of LOMO, which has now reduced the production of microscopes by 95% and only sells cheap and medium-sized China under its brand, winding up at a price of 200-300%. Samo makes only some expensive microscopes such as Mikmed-2-11, Polam-R-312 old brands. Nothing new has been created, all new models over the past 5 years are from China (including the stereo MSP-1). There is no one to work - and the premises are rented out.

ALL microscopes allegedly made in Russia at a price of less than 150 thousand - China.
Lytkarino is THE ONLY exception. MBS-10 has been produced for more than 30 years. 24-month warranty and NO complaints. Lots of calls from people who got burned in China. Even in tenders for MBS-10, these models do not pass, although we can say the same characteristics.

The only problem he has is lighting. Switching to halogen lamps, they first supplied normal lamps, and then began to buy ordinary ones with a beam of 36% instead of 10-the result is a loss of 60% of the light to heat the illuminator casing. It is treated either by installing a normal lamp of 10-12% or a regular table daylight at 11watt. There is also a good option to illuminate with an LED lamp that fits perfectly into the illuminator bracket.

As for the MS-2 optics, I won't lie, there are no clear data. Only subjective ones. if you remove non-used microscopes, then at the level of MBS-1 and even worse. And then an important detail-a feature of BINOCULAR microscopes is the importance of adjusting the correct convergence of rays. In China, cheap microscopes simply do not do this. You won't know it right away - your eyes will adjust and bring the two images together into one stereo three-dimensional image. But the result of working with such a microscope for your head will be deplorable..

Nikolay, can I tell you a little more-what can a long work with an unjusted binocular mean??

Nikolay, can I tell you a little more-what can a long work with an unjusted binocular mean??

Headaches, rapid fatigue, decreased vision.

Is that enough?
