Thanks Chris! Working with flat large specimens, yes I think those cylinders will be a huge pain... perhaps some silicone tubing might work. Must experiment. I'm currently thinking of photographing things smaller than the front lens diameter so just making a fairly long cylinder tacked on the object...

Gosh, I'm so bad at verbally describing things! Well, I'm thinking of this kind of setup. http://www.photomacrography.net/forum/userpix/5919_IMG_1824_1.jpg Those ELWD objectives, even with the 60x have ample WDs. I've enjoyed using the non-BD versions in the past. But I'm currently mulling the possi...

Since you already have a nice setup, what happens if you add a small cylindrical diffuser just outside of the image illuminated with the BD light path? (Perhaps a miniscule semi-transparent sphere like a miniture ping-pong ball would work better?) I sometimes see star shaped points of light in BD im...

Splendid comparisons!
What are the magnifications you worked with here? I tend to see low mags in brightfield with lower contrast (probably internal reflections of the objective masking the sample reflections), but that improves with higher mags (higher NA).

Cheers,
John

Wow, a private Axiomat!! Congrats on your acquirement. Sadly the manuals and brochures of the Axiomat I have don't shed light upon what that mount is... From the 3 flanges and the seemingly narrow optical path within I'm guessing an ENG (B4) mount used in video cameras. There are various adapters fo...

Hi, that's a super nice print! One thing, if you're going to use high wattage illuminators, you'll have to be careful with interference filters at the LOMO slot filter position. Of course it depends on how good the IR filter is at the lamphouse, but they don't like to be hot. Plus, in the original s...

So when we have a Nomarski prism, it's the front interference plane of the objective-side prism that must coincide with the objective rear focal plane - not the prism itself. Correct? Exactly. I've had the same problems in the past with DIC schematics showing Wollaston prisms in a Nomarski setup. A...

Yup, the beta angle and section angle are the same and they determine the distance of the interference plane to the prism. I've tried it with different prisms for reflected DIC as objective prisms and none of them worked. I've also tried my Oly U-DICT at different positions trying to improve evennes...

Well, the main parameters for making a Nomarski prism would be the apex angle (alpha) and the section angle (beta). Shear amount is dictated by the apex angle, and where the interference plane comes, by the crystal(mostly quartz) axis section angle. http://www.photomacrography.net/forum/userpix/5919...

To align white light epi-illuminators for Koehler illumination, one could place a mirror at the objective side, focus on it, remove a ocular and inspect the conoscopic image at the BFP of the objective. You could also use a phase telescope. If you can see the LED die, or bonding wires in the image s...

As of 28th, Jan. 2019, ALL SOLD
Thanks for watching!

I'm currently clearing out my drybox and have some Nikon objectives for sale. Mostly Nikon biological, but if you have any particular objective of interest (i.e. metallurgical) I may have it available. Please ask. I'll ship from Japan using EMS. 1: Nikon NCF Plan Apo 60x NA0.95 Used, and has some de...

John, thanks for the Polish version link. The cover looks better than the Elsevier version! Pity Elsevier doesn't carry reprints of the English version as they do for other legacy textbooks.

Thanks guys, I've seen those insane prices on Abebooks and Amazon.
That Optica Applicata link is interesting, I'll get some good reading time browsing those...

Does anyone have a spare or unneeded copy (Vol1~3) of Advanced Light Microscopy by Maksymilian Pluta?
