Olympus IMT-2 mystery

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...

Re: Olympus X-Line Objectives

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.

Re: Centering & adjusting the Leitz 100Z lamp?

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 ...

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.

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.

Re: Chromatic aberrations filtering

Apochronaut’s comments are wise , and well-expressed. To the best of my knowledge, software fixes can only work by discarding information and/or making guesses.
