The objectives on the microscope in the photo are from the later model -2 series. The Vanox AH used the shorter barrel 36mm objectives while the next generation used the longer 45mm barrel objectives. There is not enough adjustment room to accommodate the longer barrel objectives.

Led conversion for Axiostar Plus

Hello all, I've done quite a few LED conversions and the Axiostar Plus is good candidate. I have a conversion kit (110V) that easily goes in the position of the circuitry of the scope and powers a 1W LED that is sufficient for bright field applications. I also did a project using an LED with variabl...

Jose, Since you are in the US I can offer the next best thing to a test drive. That is a connection to several professional microscope service dealers who often have reconditioned instruments in excellent condition. Moderators, if this is outside the limits of the group please amend as necessary. Gary

Hello Jose and all,

I have had the opportunity to work with and on both the microscopes you have mentioned and my vote, for the reasons mentioned by Ichty, is for the Olympus BH series, in which ever form you choose.

I was just doing a bit of browsing and read this post. I've had one of these cameras for several years and it is great fun. I hang it on the bird feeders and am always amazed at what I catch. The candid photos catch behavior traits that cannot be appreciated in a discussion or lecture (ornithology c...

Hello Sebastian, You should check the torque on each of your control knobs as well as the meshing of the racks and pinions of each axis. If Y control is causing movement in the X it may be because the X is too loose. More likely it is the spacing of the racks and pinions. While holding the selected ...

I am coming into the discussion a little bit late, but maybe not too late to get in on the home brew. I don't have any manuals but do have lots of experience working on the stages and specimen holders so if you still have questions I will be happy to help. As for the Nikons with 2s in their names; t...

Although I do not recognize the specific brand of your microscope I am familiar with many of the components and design elements. I believe that this family of microscopes was manufactured for and sold to a variety of retailers. The coarse/fine focusing block appeared on Kyowa and Bristol / Bristolin...

I'm glad Charles is in on this discussion. He types a lot faster than I do and is saying exactly what I would were I not so digitally (fingers) challenged. The more expensive microscopes you mentioned are not much better. They still have the same focusing design and lots of plastic. The mechanical s...

Hello, Not knowing where you are or what limitations you face regarding prohibitive shipping it is hard to be specific with a recommendation. It would be much easier if you had a model and photo that we could look at and evaluate individually. Having said that, I will climb onto my soap box and opin...

I have seen these microscopes, often under different brands, and believe there are many better choices for an inexpensive elementary microscope. They are mostly plastic in their focusing mechanisms and not very precise. There just aren't many good things to say. However, the question remains. Is any...

Hello,

I've had a lot of experience (professional) with this model and would only give it one star. There are many scopes at this level that are quite a bit better. Of course, if it's the only scope available one could argue that it's better to have any microscope than no microscope.
