Thank you for this test. It is really helpful (i have been one of the guys suggesting that the superwide heads might deliver better quality at the edges of the image but never had the time to formally test it). Officially the TLU is for 22 mm but it odes not surprise me that it works beyond that. ma...

I have no first hand experience but LM Scope was the company our Olympus technician recommended as first pick for DSLR adaption. Also said that they provide excellent support and reccomendations.
They are pricey though.

If you have Phase contrast a PH3 or PH2 ring should also provide DF on 4x.

I cannot agree more with jmc and others. you should be careful with what you do (and follow the instructions in the manual closely). There are some specifics like "not touching the glass" and not looking into the unshielded lightsource that come with using a arc source. Osram ans Ushio both make bul...

Spectacular images. Thank you for sharing.

The Olympus BX45 and its successor BX46 are modern examples of fixed stage, moving nospiece designs.
There is also an attachmet (WI-NPA) for the BX51/BX61 (and 53, 63) upright that mounts the nosepiece on the stage mount to allow fixed stage designs (used in the water immersion design BX51wi).

Dear fellow microscopists, i have not come around to post much content in the last months, even the last year. For one, I have the pleasure to enjoy working with a microscope all day; also we have moved into our house just about a year ago and there is still just so much that needs to be doing. My m...

In retrospect I am glad I never got mine because if anything goes wrong with the electronics, then I am stuck with an unusable scope that takes four times the desk area of a BX. One of our Oly reps told me a story about an ax70 dopping from a warehouse storage shelf, knocking a hole in the concrete...

I tested drift on my bx43 (with (30w equivalent) led light source) on two occasions. In both it lost focus within a 15-20 min period (no-touch and no vibrations, i was out of office) with a 40x/0.95 objective. The scope likely was in thermal equilibrium (it was running all day and there was little t...

Turn the microscope sideways or upside down and see if the drift changes direction. Im not sure if this will work - i think the bx stages are "preloaded" by gravity. I cannot really turn my scope on the side though. sorry. I did a quick and dirty test today and the focus shifted a relevant amount d...

Wonderful images. Thank you for sharing!

It would be interesting to do some testing on your scopes, setting 100x objective and leave it for 10 minutes see if you get a drift too?

What lightsource do you use? (LED/Hal/etc.)
Epi or transmitted?
Constant illumination or only on during camera exposure?

Just in case, check the friction/brake on the focusing rack before you do any maintenance. This lever may be set too loose. The lever that controls friction is located between the left coarse focus knob and the stand. I agree 100% with enricosavazzi (but i think this is what adamski ment with "I ti...

Hi, drift through the fine focus can happen if the fine focus shaft is not properly lubricated. It needs (quite stiff) dampening grease. Unfortunately Olympus does not tell you which. Maybe try to lock the fine focus drive in place. Pushing a hefty weight (e.g. a metal block) with some rubber to the...

And here I am doing something stupid. Didn't slot the prism into the holder correctly, rubbed some of the anodising off and made a permanent mark on the lid. :oops: These universal condensers are a pain in the #####. most of my prisms have marks from rubbing against the condenser turret lid. Your s...
