This is for infinity systems, so presumably, a type F head for 160 tube optics, such as the Optiphot and Labophot series is not suitable. As a general question, perhaps someone can clarify where the telans optics or tube lens, whatever you wish to call it, is located in the Nikon infinity systems. ...

Thought I ought to report back. The one from Bristol cameras arrived in just a few days, and fits fine. Since the ones from China were only 99p each, I ordered the pair as suggested to do it in 2 stages. Unsurprisingly, these have yet to arrive. I will let you know how I get on with these. Thanks fo...

Thanks, ordered from them. At least I won't have to wait for the slow boat from...

cheers

I am trying to find a ring so that I can fit an accessory that is 42mm screw thread (male) to a filter thread on the lens (female) of 46mm. Many vendors seem to be very confused as to whether they consider this a 'step up' or 'step down' model, with one contradicting the other. However, even searchi...

I guess that we are going to find them mentioned in older texts such as Lefkowitz, and others(*), as they were commonly found lenses at the time, but not now. Trends in photography change, and many that come to it via modern digital kit get such good results in general use that they don't even learn...

Hi Guys, I'm searching for a list of compatible condensers and objectives for a Leitz 170mm Orthoplan. I see condensers on eBay and Polarising sliders, etc. But I cannot seem to find 170mm TL objectives with matching wollaston prisms. I can find plenty of infinity corrected ones though, like this: ...

Are these 21 mm long?

Really enjoying the discussion - and interested in the shift to 6K mp4 collection of extended focus stacks. I've been using extended focus to image small liverwort plants, an offshoot of our research in Cambridge, where microscopy plays an important role in integrating genetic, cellular and tissue-...

I remember reading on one of the Olympus web pages that one can use a "special objective" designed for centering epi and epi-fluorescence microscope illuminators. The page did not discuss how this accessory works, nor its technical name, nor an Olympus model name or number. I assume this is an acce...

Hello Forum, I'd appreciate tripod recommendations for a Lumix G9 + Olympus 60mm macro (total weight = 840g). The tripod needs to be as light as possible because it would be carried in my backpack during long days in the field, often up big hills. Many thanks for any help. Cheers, Des :D Hello Des ...

A fascinating and very useful result. Standard [No. 1] cover-slips are often said to be 0.13-0.17mm. I have no idea whether the slips really do vary so widely in thickness, either within a batch or from batch to batch, but if they do maybe a micrometer could be used to identify three thin slips to ...

Yes, nice image. Lichens, and mosses and liverworts do make good subjects, where you only notice some of the detail when you look close. This is tuft of moss, the anomalous bristle-moss (Orthotrichum anomaly) which is around 1 cm high, perhaps slightly more. I have just realised this was taken in th...

One is a wild heerbrug prism ring, maybe some kind of vertical illumination beam splitter for stereo microscope? Yes, I think it is intended to illuminate in between the optical paths. Yes, Zeiss made a similar (almost identical) device for their stereo models. It screws to the lower ring, and you ...

Unfortunately this is very much the case.

Two views of the same diatom (Pinnularia sp) of mine had very differing hits. It took me a while to realise the most popular (by 20x) was merely because it was the girdle view.

Sad in many ways.
