Hi Phil, The INKO condenser generates an image of the interference fringes of the DIC prism in the back focal plane of the microscope objective. In order to achieve that, the condenser prism has to be positioned in the front focal plane of the condenser (Wollaston prism) or just below or above it (N...

Hi; Zeiss built a huge range of microscopes, so before we start it would be helpful if you posted an image of or link to your "Zeiss stereomicroscope 10-40x". Also, do you want to take images of the insects (which taxa?) for their aestethic value, possibly using stacking, or you want to just documen...

Hi RL, I suspect that the flange focal distance of the U-III film holder is quite short. You have to keep that in mind. http://en.wikipedia.org/wiki/Flange_focal_distance Another point is that the electronics in the unit (meter, shutter) are now all integrated in DSLRs. It makes units like the U-III...

Hi, I don't have a manual but in this brochure you can see the capabilities of the Nikon U-III system. http://www.atscenter.com/home/product_data/FX-III.pdf It might have been great at the time (film cameras) but you have all these functions integrated in modern DSLRs! They are the way to go if you'...

Yeah, I wouldn't change the tube length for more than 2mm. +/-2mm is the only length change that I now of, that had been "accepted" by a microscope manufacturer (Leitz; using (high power) 160mm objectives on older 170mm stands and vice versa ). This, by the way, was my idea; using a Nikon head on a ...

Hi, Thank you for taking that measurement for me! That distance is relatively short compared with other manufacturers. Unfortunately for me that means that I cannot use a Nikon S series trinocular head on another microscope (using a dovetail adapter), as that would mean that the assembly exceeds 160...

Hi, Does anybody here have a black Nikon S series microscope and could take a measurement for me? I'm looking for the distance between the top of the tube head (after removal of the binocular head) and the bottom of the objective turret. In most microscopes, it will be around 40 - 50 mm. What is it ...

Very impressive! How big was it, and in what habitat did you find it?

Great idea!

Hi Walt. I have the condenser and the intermediate tube but not the lens. My understanding is that the lens is needed as an accessory lens in front of the condenser to fully illuminate the field with the 10x objective; so I might be able to substitute this easily. Tellingly, the set came only with t...

That you for the tip; it should fit on the Apophot. Do you know it there are any other (smaller) microscopes what would also work? The Apophot is a bit too big for me

I would not have thought that Nikon handled the cells during assembly without gloves so suspect that the objective had been opened before. Indeed. In image 6, you can see 4 bores. As far as I know, these would have held little plugs/spacers inserted in the factory to achive axial centering. If anyb...

Dear all, I had the good fortune of finding a 1960/70s Nikon Model T DIC set (condenser and intermediate tube). It's from the time when Nikon made their "black" microscopes. However, I don't have a microscope on which this set would fit straight away. So I'd either buy a stand on which the condenser...

¿Surely duodenum?
