Re: Microstar IV LED Illuminator

I recently completed nearly the same retrofit. Yours is a much more polished implementation, I must say! I used a Cree XHP-35 topping out at 12W, but the smaller die should be very close in size to the original filament. (More knowledgable people people than I suggest that is important to retain per...

Re: Converting a Nice BH-2 into a Nasty Frankenscope??

It’s a testament to how rigid the Olympus stage is that you could get clean cuts with it held in the mill that way. I would have thought it would chatter like crazy cantilevered so far from the vice. How deep was each pass?

Re: Beam splitter optics problem?

When I opened mine there was evidence of water intrusion. (I hope it was water!) I think that may have cause the silvering to oxidize from the edges in.

Does parfocality matter here?
There are 37mm and 45mm parfocal objectives that all conform to RMS- or DIN spec.

(Just don't mix them or you're 'screwed' :lol: )
D.I.N. specifies 45mm parfocal distance. J.I.S. specifies 36mm distance. So to conform, yes, it matters.

Re: Beam splitter optics problem?

Re: Beam splitter optics problem?

Both heads have a completely formed image. I’ve only had the camera on the “far” head. Since I’ve been trialing different camera set-ups, I’ve been assuming any aberations are related to that. I’ll need to swap heads and see what there is to see.

All I know about this scope is that it is a Spencer AO 1036A Welcome! A bit of trivia perhaps, but as Apochronaut said, this is an AO Series 10. 1036A is actually the model of Illuminator. That's a decent condition older series 10. It dates from about 1970, likely earlier. Are you basing the age es...

Re: Thoughts on a reducing relay and a higher mag photoeyepiece

Shouldn’t it be possible to raise the 3.3x very slightly and move the camera closer to it? That would be similar to how a 10x eyepiece is used as a projection lens. The adjustments would just be smaller.

Re: AO/Reichert One-Fifty vs. Reichert-Jung Series 150 differences and head compatibility

That's from the fairly rare Plasterer's Microscope. It was only briefly catalogued.

It had a ...

Re: AO/Reichert One-Fifty vs. Reichert-Jung Series 150 differences and head compatibility

I agree that looks like a 150 style head. The finish on it has alarm bells screaming, though. That can’t possibly be a factory finish, can it? To me it looks like an old beat up grey head was refurbed to match the new color scheme. The masking is poor. The texture obscuring the diopter grip seems wr...

Re: Curious if anyone recognizes the camera adapter tube on this Reichert 410

A whole bunch of proprietary photo lenses are going to over correct in your system. Putting a # 181 or 145 about 180mm from the second telan lens should give good results. I thought the lens (Oly PE) might be the problem, too. I tried a 181 in its place (literally same location) and was surprised t...

Re: A.O. bits wanted

I’ve used it a little with a 20x on my series 10. You don’t get true Darkfield. They are good for higher mag objectives that won’t work with patch stops. On the flip side, for the 20x you should be able to get good results from well made patch stops.
