Voui...
Mais si les molettes en plastique cassent, BelOMO n'y est pour rien, c'est un défaut de conception, et de simplification à outrance de certains composants chez Zeiss (et autres).

C'est une question de cahier des charges... honte à Zeiss
(vu le prix qu'ils vendent leur camelote, ça leur coûte quoi de mettre des plastiques qui tiennent la route ?)

Bonsoir,
Savez vous comment la molette a cassée avant de critiquer?

Very Interesting photograph, indeed!!!
I had thought ,, that the lowest price Zeiss scopes were built by Motic. It is possible the optics come from Motic and the stands from Belomo. I have one such stand at work and will look for an origin label on it. I will report back later.

Both Belomo and Motic are capable of excellent quality. But I agree. Zeiss charges too much to put their name on a plastic inexpensive scope. I feel the same way about he Stemi 1000 and 2000 scopes. The 2000 s I have examined do not say "Made in Germany" on them.
Usually European , American and Japanese made products brag about their origin. Sneaky mislabeled ones do not

The one we have is also made in Belarus. The picture shows lots of stands and no optical heads. It think those come from Motic.

Plastic gears and wheels can be almost as good as metal. If they are correctly designed.

In the late 1980s Wild Heerbrugg started using plastic focusing racks on their Stereo microscopes.

I have serviced a large number of these that were in student university service for twenty years. They have worked very well.

I was very concerned when they first came out. They replaced stainless steel posts and ball bearing slides. But I have to admit they work pretty well. Even twenty five years later.


Of course so have the M5 s we have that were made in 1966. If the lubricants were not allowed to solidify they all still work very well.
Almost FIFTY years later.
