I still have not figured out how to post images into these threads … . It would be very helpful if you could ^^^ The process is relatively simple, but only permits the use of small file sizes At the bottom of the composition-pane, there is a tab labelled Attachments via which you can insert images ...

A different mystery today … How do I free-up the CT focus ring ? This is stacked above the Magnification Changer, and illustrated in the exploded parts diagram: . IMG_9342.jpeg . But it is not obvious how it actually operates. … The two rings currently appear to be locked firmly together, but I susp...

Thanks for posting that, Pete
… I understand a little better now.

CK40-EPA is mentioned twice on page A-3 of this document,

… but frankly, I don’t understand what they are saying

MichaelG.

Nice !

Please forgive the slight digression, but this paper is rather impressive:

Hi, […] but usually, they seem to be described as being short. Here you see the difference of cilias length, of the same protozoa, my camera/video/setup not being able to catch the details at such high speeds: […] You make a very good point … but perhaps that ‘short’ description reveals that most p...

You have a nice scope in your hands there! I like the IMT-2 a lot.
[…]

Thanks for the encouraging endorsement … I must say that I am delighted with it so far

… and the ‘correction collar’ adjustment for 0 to 2 mm glass thickness is astonishing, and effective.

I hope these snapshots will clarify The housing is simply a shielded and ventilated box that clamps on with a single knurled screw … beautifully built, but just a cover. The bulb-holder is a fixed installation in the frame of the microscope … the white wiring can just be seen in one image. In short,...

Thanks for the sanity-check, Tom

… I wonder how many they made
… or how few

Do you happen to recall the serial number of yours ?

MichaelG.

Michael, Fig 20 on that list hints (maybe) that there was more than one illumination housing. So, while a 50W lamp seems the default, perhaps there was a 100 W - for more demanding modalities ? fluorescence with a 100W halogen lamp comes to mind, although the during the IMT-2 era, epifluorescence w...

Indeed it does, Pete

In fact it explicitly states LAMP 12V 100W

MichaelG.

This looks pretty close !

MichaelG.

Michael, I suspect your scope should have the black metal 50-watt halogen illuminator - and that someone switched lamp housings along the way . If you check the electrical plate for your scope, it may shed light (metaphorical kind) on what lamp wattage the power supply can reliably support. If the ...

Thanks for the comments, and the link Just to be clear … my IMT-2 has no umbilical, and no provision for plugging one in. The lamp is powered internally … which presumably means that microscope PSU design was upgraded at some stage in the product development. It may be worth mentioning that the Seri...

I have recently acquired a fairly basic IMT-2 which is causing me some confusion The Halogen lamp-house looks very much like the one for the BH-2 and does not have the very distinctive umbilical cord that seems to feature in all the available IMT-2 literature. It is also very clearly labelled as usi...

Thanks, Pete … I suspect we will see more reactions in similar vein.

The video was just included in a very friendly, but ultimately not very helpful, response to a question I asked about my recently acquired IMT-2

I will start a new thread on that topic.

MichaelG.

This is very impressive
… Keep up the good work

I received this promotional link from Evident, and am posting it here for general interest/discussion https://view-su3.highspot.com/viewer/66045456bc8bc3417086b790?iid=635b9ea473b518b8afacceb5 MichaelG. . Edit : __ This ‘white-paper’ contains more technical detail https://static2.olympus-lifescience...

Is your Orthoplan a standard instrument, or a ‘bitza’ ? [ bitza this, and bitza that ] It looks to me like you need to first make some reasonably simple measurements of what your illumination system is actually doing … and then compare with those listed values. Note particularly the reference to IV ...

Does this come with objectives?

Not by my reading !

Included is also a 7 position nosepiece and binocular head, but no eyepieces. No condenser or optics are included in the sale.

Hello,

How do I center and adjust the lamp on a Leitz 100Z lamp when there is no adjustment disc?

You should be able to make a replacement disc from a sheet of tracing paper or similar
… it’s just a target; the screws do the adjustment.

Alexander beat me to it !!

I would recommend watching Part_1 of that YouTube series by ‘Gordon’ to get a good appreciation of the whys and wherefores

MichaelG.

Just one thought … my reading of the Amazon listing is that it turns at 1-2 revolutions per minute !

If I am correct, that is very slow for the purposes you have in mind.

MichaelG.

That looks like a very useful/useable hybrid … nice find !

MichaelG.

Well done, Don !

MichaelG.

Hello, Don

I have just looked-back at some of your videos … they appear to be on YouTube
https://www.youtube.com/@DonSchaeffer-ew3dz

Sorry … I don’t use it myself, so can’t help regarding your log-in problem.

MichaelG.

Interesting to note that the designation for those two includes UV … but doesn’t mention either LWD or ULWD

… looks like a long and winding road ahead !
